IOM Worlds : Parallel Scoring 5 – Standard Redress Processing……!

The photo above shows you our Scoring Team’s Process Crib Sheets. Note … taped to the desk (cleaners came every night), and angled in to the HMS Scorer position. We did a lot of preparation on “process” and we shall write about the importance of that in another article. There are three process sheets here:-

  • end of heat backups
  • end of race backups
  • end of race results publishing

There is of course one missing.

Standard Redress processing.

It’s missing because none of the Team, including me, understood in advance quite how important the work around Standard Redress was going to be. It’s massive.

It’s best tackled not at the end of the penultimate day… but in every race as you go through the Championship.

Most of us had never seen fully Umpired racing before. Interesting experience.

When the Umpires deliberate, a possible outcome is that an aggrieved party – knocked to the back of the fleet perhaps – can be awarded a “Standard Redress”. It is widely acknowledged by the Umpires that the HMS Excel scoring system does not have support for Standard Redress. This type of redress includes future score averages in races after the redress was awarded. It will be a manual calculation for the Scorers to complete after the last race of the penultimate day (look up on google or IOMWorlds2026 Jury Notice 1 for the Worlds). Redress awards given on the final day can use the standard HMS Excel button for “RDGave”. HMS Excel calculates redress awards looking backwards only – not into the future.

In UK, where use of HMS Excel is the norm, as there is no tool for Standard Redress we have a tendency not to use it. At the IOM Nationals we processed one. I’d not seen one before.

To be honest, it’s a very manual and error prone calculation. Get your calculator out and try one.

At the Worlds, after three days the Umpires had awarded three standard redresses. Concerned about what this would mean for workload at the end of the penultimate day:-

  • racing ends around 1830
  • scoring completes and winds down about 1900
  • 1-2 hours of standard redresses to calculate, check, check again and then apply to HMS Excel
  • drive home (1-2 hours)
  • eat main meal of the day
  • go to bed
  • get up at 5am and do it all over again

… so I emailed the Umpires to “alert them to Scorer’s concerns as to the viability” of averaging one Standard Redress per day.

In the next two days of racing the Umpires awarded another 7 Standard Redresses. So we had 11 in total, two of them with one competitor. I had brought my Casio calculator and a ruler just in case….

Essentially for 12% of the fleet, you pop them into a boutique scoring system of their own. We had to separately hand calculate special scores based on ALL heats to date, check the rounding to 0.05, remembering which scores to exclude. (a competitor with two awards is a trap!) Then you have to apply the WORSE/BETTER score test to each Redress … then decide whether to apply to or not …. then load the answers into HMS.

Then ….publish race results to competitors so they knew exactly where they stood going in for the final day.

If you’ve read this far, you’ll understand the Scorer’s alarm.

So what did we do??

In flight, we designed, built, tested and used our own Standard Redress tool in Excel on our fourth laptop. We kept it up to date as Umpire decisions arrived, and race by race. At this award rate, no alternative really.

You can download our Standard Redress tool here on this link.

You are welcome to use it. If you discover an error, honestly… don’t tell me.

Points to note:-

  • every skipper with an award is tracked through the entire regatta, race by race
  • when you get an award in race N, you have to dig out all the scores in Race(1-(N-1))
  • watch out for the result exclusions
  • a skipper can have more than one award (see CRO33) and you have to cope with that
  • rounding needs to be watched
  • BETTER/WORSE Test needs to be applied

There’s a lot of calculating in there and you will see for each competitor, we ran the BETTER/WORSE test manually.

Before you load these Redresses into HMS, you need to audit them carefully. There would be hell to pay if one of them was wrong – Race Team protested etc. So how to do that audit?? The Casio Calculator??

You will note in the spreadsheet that each awarded competitor was audited (checked) by AFleet. AFleet happily has a Standard Redress button and we used it to check the answers our new tool was producing. You will see them there coloured black. Only when everything agreed, did we release the calculations for processing. Did AFleet find an error in the spreadsheet?? Yes – one. It might otherwise have snuck through undetected. But we found it.

Thank heavens for Parallel Scoring, eh??

Funny side-story :

This was a feverish work session and the whole team was ultra-focussed on their own contribution. Intense, it was. We hammered through all the processing and safely got the correct double checked answers keyed back into HMS Excel. Then I said to the Afleet scorer, “OK that’s done. Let’s do the same on the AFleet results now.” My colleague looked at me blankly and replied, “No … I finished all that ages ago….”

It built a little tension into the Umpire-Scorer relationship, I can tell you. In a very kind gesture, the Umpires presented us with gin and fruit cake. They were OK guys after all !!!

IOM Worlds : Parallel Scoring – 1 …Why Even Bother..??!!

At your Club, are you heading towards hosting a large Championship soon?

Obviously when you’re headed towards hosting a Worlds as we were, you start thinking about the BIG questions a year or two ahead. You’ll know already that Datchet tried to always have at least two ways to do any single job at the Worlds. Does this approach apply to Scoring?? … Hell, YES !

What are the really big questions to consider in Scoring? Well, for a start you have 84 people about to arrive who have spent a lot of money to come and race with you for a week. At the end of the week, or at the end of the Championship, regardless of the week they had, they ALL want to see their name on that Results Listing.

Yes – On that last day, 84 “experts” will all gaze at the beautiful printout that you have pinned to the Official Notice Board. They expect two things –

  • it’ll look smart and professional and their name was correctly spelled
  • It will have precisely ZERO errors on it. If they find an error at that point, especially in their own score, your name will be MUD. The subject of clean results, as it happens, is a whole new thing if you Parallel Score.

Reputation Protection – The Big Issue:-

Selfishly, for your Club you should be thinking of protecting the Club’s Reputation. It takes years to build up a reputation to be considered anywhere near “capable”. As we all know from 2025, you can destroy Club reputation in a flash. Reputation takes years to build and just minutes to destroy. If Scoring were the perceived failure point, it’ll take less than a few minutes to destroy. It’ll be talked about (with sniggers) in Club bars across the world for years.

Within Scoring, everyone will tell you “it’ll never go wrong”. …. “one in a thousand chance…” etc.

Don’t you believe it. What would you do to protect your Club Reputation?

In considering Parallel Scoring, we would consider it :-

  • for a 30 Boat Event? …. Probably, No
  • For a 45-55 Boat event? … Well maybe
  • For a 55-84 boat event?… Yes, for sure.

A simple way to think about it? If the scorer or scoring system fell over on the Penultimate Day, could the Championship recover by some other means – even paper scoring?? If you have already entered a couple of thousand boat results, just think what it means.

In 2024, we made the decision to score our various upcoming Championships into two separate scoring systems at once. We called the technique, “Parallel Scoring”.

Not simply having hot standby laptops and USB sticks…. but two systems at once.

Does this mean double the work? NO.

Are there surprising benefits? YES!!

Which two scoring systems? Everyone wants to know. Regardless of if you’re racing to HMS Rules or SHRS Rules, you should first think of what volunteer skills and platforms you can access locally. Start there.

At our Club we had people with knowledge of three scoring systems for heat based racing – the MYA’s HMS Excel, HMS on AFleet and HMS on Andrew Crocker’s brilliant Fleetboard. These are three really good scoring systems. We were spoilt for choice. We shall write more on the website later about why we chose what did …and probably it will not be for the reasons you expect. …Start with the volunteers you can get and the scoring skills that they have.

Consider the technology skills you might need too – I was keen to have a team member who is a Microsoft Professional for a living. How fantastic that turned out to be.

When you choose both your scoring systems, remember that if the two systems do not run on entirely separate technologies…. there is really no point.

When you later read our analysis of the things that can/did go wrong, you’ll fully appreciate the depth of the issue and separate tech.

We felt it natural to choose HMS Excel as our primary system and then Afleet as our Parallel System.

We decided with the PRO that unless we had a catastrophic situation, official results would simply always be from our primary platform – HMS Excel 2022.

Datchet IOM Worlds – Coming Up….!!

It’s 3rd June. About ten days after the Worlds.

We are nearing the end of duties now. For myself, I’ve put the scoring systems away (the team are having a lie down!) and I am working hard to close the Championship accounts, …and already we are helping re-use the Worlds legacy knowledge to support Jim and the boys running the DF65 Nationals this weekend coming. Good luck to the East Kent Members at Barton’s Point !

In the rear view mirror, you get to appreciate how much we have learned putting many months of hard work behind us. In the coming days and weeks we shall look to reflect and digest – and place some of our knowledge on this website to help other Clubs run their events. In coming weeks, we are thinking of reporting to you on:-
