Which Clubs use modified PY numbers

Starcross YC do - we are just starting the third year of local adjustments

We review them every year in late August and apply them from the start of our Autumn Series in October each year.  The analysis compares the data collected in the previous year against the RYA numbers, the Great Lakes numbers and our entire database going back 4 years.  We also do an analysis based on the top sailors in each fleet. [Once the RYA releases the "clubs like mine" facility on PYS we will build our own custom group of similar clubs].

The numbers we use are shown on our results pages - but when I update the numbers in our race management database this month I'll sort out a page on the website with a list of them.

We are a little bit tidal so as you might expect in general the faster boats go down a bit and the slower boats go up a bit - we don't analyse it that way, its just how the numbers pop out.  The Laser and Laser Radial have the biggest change from the RYA numbers - but are close (a bit faster) than the Great Lakes numbers.  The difference between our numbers and the RYA used to be quite big, but they have got narrower since the PYS related approach has been adopted and the RYA numbers have moved closer to our locally adjusted ones (with the exception of the Laser).

Rutland do 

Jim, if you adjust for some (where you have the evidence) but boats which were having close racing with the ones you have adjusted (maybe against the run of other results) don't have the numbers to warrent a change, what do you do?

I suppose an example which might happen (just to try and make myself clear) is that if you have lots of Solos and just a couple of Lightnings, which get close results, and are close on handicap. The Solo results, though, are too good - the handicap needs a reduction to fit in with the other big fleets - say Lasers and 200's. If you leave the Lightning where it is, due to lack of numbers, suddenly you would have shifted the goalposts for 2 very close boats.

Do you have a solution to this?

I can see it happening in the winter meetings, where I think the Solo has gone the other way. If I arrive in the Lightning, expecting to find I have a close race with the Solos, but then find they have been moved up 20 points, but mine is still the same due to a lack of results. I'd be somewhat miffed.

Nice to see Starcross doing a comprehensive job of adjusting. It's good to see others having a go too.

HISC do.
Not sure how they are worked out though.
