I dunno ... but my point is that that would actually be a qualititive experiment to genuinely carry out before writing off the concept altogether as ‘unworkable’.

But hang on - if it was not for some form of Handicap system I would not have been out sailing against 100+ random people on Draycote. It was the handicap system that enabled me to turn up and take part, otherwise it was just a random days sailing on a lake in the midlands. However flawed the system is it enabled me to have a great days sailing! |
True - although the irony of it is that the handicap system bore (little to) no impact on said day; so in effect, all you were doing was a day out sailing with 100+ random people in the midlands whether you like to admit it or not. That being the case, why not ditch the handicap system altogether and just arrange it like a festival of sailing in broadly aligned categories, free from this overly analytical BS that is supposedly the future of dinghy sailing?
|
Lets just agree to disagree. To me it was a great day. To you it was a waste of time. Perhaps that is why I showed up and you (I presume) did not. Future of sailing or not, at least 100+ boats showed up and only the Toppers had more people at their Nationals with the RS200, Solo and some RS Youth fleet getting close on turnout. My point is that people seem to be voting with their feet and showing up to Handicap races in a way that they are not for fleet racing. Maybe you'll have to give it a try soon?
|
I never said it was a waste of time, I simply point out the bleeding obvious that tinkering yet further with the handicap system will not change the fundamental issues with it. I know draycote run a good event ... and the wind played ball, so no not a waste of time. Just a nice day of sailing all the better for a good class turnout in your case - but when it comes to the actual racing, i just put emphasis on your well written descriptions of the boat on boat interaction than I would on the spreadsheet- interestingly the oringianl article referenced in the OP doesn’t even link to the results, so it not like the author is putting much emphasis on it either 😘

Sam - just out of interest does L&L use RYA, great lakes or some modified list for handicap racing? Reason I ask is that SCSC where I sail uses a modified RYA set of numbers and I was wondering how common this was?! |
RYA PNs adjusted in accordance with the PYC guidelines I believe. Phantom's on 1014 this year so +15 (no wonder the buggers are so hard to beat  ), Lasers -15, Radial -17 (we have a strong fleet who race within the Handicap during the main season and fleet race over the winter). Blaze 1027 (no adjustment yet but we only have two and I don't race all that often to help generate the stats).

I enjoy handicap racing, I just started the thread to understand how the new system works because the article describing it is short on detail. One advantage I can see of judging you on your best lap is that you are never out of it even with a bad start and a capsize at the leeward mark, you just need one good lap. The disadvantage is that you can’t even guess how you have done against the opposition until the spreadsheet spits the results out.
The most appropriate handicap system depends on the event. If you want to attract the best sailors to come you need to give them a fair (equal) chance of winning. If you want the middle rankers to show up you maybe need to randomise the results a bit more (to give a chance of outperforming their expectations).

What I'm getting at, is do you know what went wrong in the race you came 62nd? Where did you lose those twenty places? Or conversely where you gained them in the 42nd? Did you actually perform quite well in the 46th, making big gains on each leg, but just got a bad start or an unfortunate shift on the first beat? Can you correlate your performance with your result?
Those tend to be things that decide how rewarding I find the racing. In handicap racing the nuances of that get lost in the noise of different boats strengths and weaknesses. I often just end up looking at boats in my class... which makes me think, I'd be happier racing against a handful of my own class at a small open or in club racing and have less obstacle to get around!
If the new scoring, or data analysis could tell me more about how I was performing and where really I was doing well or not, then I might see more value in it.
Your results above, which system are they from? Which score (GL or Dynamic) better reflected your performance and why?
|
Yes I know what went wrong - I had a duff start and had to make compromised decisions up the first beat and then was unable to claw back much on the next few legs. I was able to visit the website after and see this happen by following my GPS trace and my dynamic positions change over each race! |
See, this is what I could see value in. I want to know more now. Which legs did you gain the most, what tactics did you employ. What did the dynamic handicapping tell you about that?
Some data output that can tell me moment by moment where I was gaining and losing, possibly with greater accuracy that my own perception on the water. If it were real time then amazing, but even as post race analysis it would be a big draw.
But I have no idea how this works out in dynamic handicapping. I'm also still not sure from your posts how dynamic handicapping varied from the straight up GL handicap results you got.
I understand you enjoyed the event, but it still doesn't help the confusion over what the dynamic handicapping adds to the event or results! Or why it should be rolled out as the premier dinghy circuit of the summer.

OK, so two or three more pages to get back to the point we were at then. People who have an axe to grind against a handicap system will grind it (ceaselessly) and those of us who accept such things must exist and a happy to get on because we enjoy the mixed competition and aren't too fussed about the overall result as long as we have a good sail.... will do our thing.
Personal handicaps instead of boat handicaps will soon fall foul to the same blah blah. In a sport with so many variables it's nigh on impossible to think of an even 75% accurate system.
Well done to those willing to try and mix things up and come up with something new. Well done to the volunteers who turn up and run the races and stick the results in the computers so we can all see them afterwards.

It would not take much to turn the GPS units into both send and receive and allow each boat to know their current position either using the RYA PY, Great Lakes or some black box formula. Frankly I would not mind much what they used. The RYA say I should race off 1037 but I actually race of 1022 at South Cerney and its never worried me much, I just get on and race.
