BTW PG, the PN list certainly doesn't have Laser down for 'just over 2000' races, the number of races returned for Laser WRT the 2018 yardstick is 25457. Only it and the Solo have more than 10k (Solo - 14628) which, considering they are probably the only boats widely raced in class fleets suggests there may be twice as many of each actually racing regularly (obviously just a guess but if we say 50% of races are in class fleets with no returns made.....).

I couldn't make sense of PY submission list either, got Laser down at just over 2000 unless it's weekly
Does that not reflect the fact that at larger more organised clubs (those likely to do returns) there are also likely to be enough Lasers to have class starts and races - so no handicap data for Lasers gets produced.

That's the whole point, you're not supposed to understand it. |

But, not all those clubs will have 400s (and some will have fleet racing for 400s) and the number of races, for it to make any sense must mean the number of races each individual boat does, e.g. a club has an average turnout of 5 x 400s for each of 100 races each year that would represent 500 races at that club...... Without more detailed figures from the PNC we'll never know.......

I think a lot of 'races' get discarded as being below a certain level of competence. E.g.if you spend a lot of time swimming and trail in 10 minutes after another member of the same class, your effort will be discarded. The laser had 25,000 races across 100 odd clubs. That's of the order of 200 'races' per club. Say 100 races on the programme? 2.5 lasers per PY race. Given that some lasers will be in class races instead in some clubs, and it doesn't include radials, that does not sound wildly wrong. Other classes, you look at the number of boats and how often they go out, and what fraction of their races will be at clubs that send returns. E.g. the RS400, 1000 or so built, maybe 500 actively sailing? The 120 or so clubs sending returns is one club in about 5 (noble's database has 800 clubs but some of those are yachts?) The 5900 races in returns would be something vaguely like 59 races for each boat in a club that sends returns?

That would add up to many more races than some boats of the PN list......
