    As an example of proposed method, comparison on results of Refeno Rally Race, with graphical presentation.

    Note two big, short-time, jumps and the influence of not-in-Series racers on SPTS, vs linear result distribution with normalized RT.

    (non-Series PTS = not SYCM or has less than 4 races finished, thus not in position for overall 40' Seies high Ranking)

    FW all!

    Cheers João & Huib!

    Ment to write earler, unfortunately no time, but maybe even better now, with current 40'Series situation.
    Before the last race, and without discarding the worst points, SimeMali (Class40) has a safe margin of 37 places behind Kipper1258 (Class40) and 38 behind psail (SOTO). With discarding, that margin is only 3 and 8, respectively. (btw. just posted race#5 xls at the usual place). Thus seems reasonably me vote for no discarding. But...

    We all know that over a 6 month period there's a GREAT probability to have at least one race ruined because of work/health/family/other reasons. João, I entirely support your goals: 'Increase the competitive edge by approximating the different levels of SOL sailing expertise' and 'bring & keep more SOLers inside', and think discarding 1 bad race does exactly that: no one is eliminated by just one misfortune.

    You bouth have right on influence of number of events and number of competitors, and I'm afraid we have here the worst case scenario: small number of races and large number of SOLers, so every point has great specific weight.

    Because of that I'm thinking about a new way of scoring in 40 Series, and realy be glad to have your opinion.

    My basic idea is a sum of normalized race times. In each race, winner's time should be considered as 1.000000, and all other race times calculated relatively to that (so we have +0.000012 for each second delay in 24h race, but +0.000006 per second in 48h race).

    Example attached is for a few boats in Refeno Rally. As you can see, boat with 0.22% (not a mistake, it's 0.0022) slower time get +28 PTS, then for further 10% 17 PTS more, and further 0.3% 6 PTS more. That distribution doesn't seems fair.

    With normalized race times, all races are equally weighted, the worst result can be discarded, and there's no cumulative delay for slower boats in longer races. This way also minimize influence of occasional, not in-Series racers on overall Series ranking.
    (This model maybe can be applicable on TR Series too)

    I'd like to hear your thoughts on this idea (and from other SOLers, oc :) ), also considerations how to handle DNF and DNS/DNC boats.

    I'll try to do a simulation of that method on current 40' Series results, ASAP (but welcome any volunteer :))

    Be well, stay well, FW!

    Mladen / SimeMali

    Hi SOLers!

    I'd like to offer somehow different view on this. With start 0.5 hr before new WX, skipper have 5.5 hrs window for routing, confusion, rerouting, decisions, DC setting, a cup of coffee with doubts, DC re-setting etc. Or simply set DCs and go to work/bed, returning to race for new WX. However, he/she can be sure for boat's course for the first 0.5 hr of the race, even with DCs set 5 hrs earlier, with no unpleasant surprises.

    We all have to get up at least once in the night for the new WX anyway (in longer races), but with start time 0.5 hr after WX, skippers get only that 0.5 hr for all mentioned above, and all prior considerations and DCs already set would become useless.

    Me think it's rather to have known accurate WX conditions on start 5.5 hrs before than only 0.5 hr, while have to check new WX anyhow. And that leaves more opportunity for SOLers to find the time and set start DCs, if needed.

    With start right after new WX, that opportunity is limited, and if skipper is unable to go online inside this 0.5 hr window before the start, that can be major handicap in this crucial part of race.

    Fair winds all!

    Hi all!

    For Q3&Q4 40' Series, here are
    Polar Performance Comparation Tables, to ease your choice :-/
    Values are from official 40ft_polars.zip, qtVlm csv. Good luck!

    Original idea and work on this tables are Renegade's, I did just update numbers. THX Renegade!
