    I understand there are glitches but to continuously show a faster boat ahead in the standings who is 30 miles behind a slower boat is quite an error, not just a few hours time variance, like 24 hours. I'm not sure how the other race trackers do it but I think it has to do with an "averaged" data set, not a single data point. Maybe a calc. if the race ended right now where would they stack up, that's a way better indicator and takes skippers and boats performance thus far, not a calc based on a few seconds of high speed surfing or wallowing between swells. If it's that off it should simply be left out.... maybe a leaderboard with only DTF, not corrected.

    Ray has set up a nice tracker with estimates also. Same data in though...

    Hi Greg,

    If you want you can take the position reports and construct your own algorithm, or just manually make a projection, build and alternate leaderboard, and I will post for you on the SHTP website.

    Regards,

    Brian

    As the public can see, but may not be able to understand, is the boat listed in 1st OA (Ventus) on the "Leaderboard" is physically 40nm behind behind a slower rated boat (Kato) who is listed 4th OA but really WAY ahead corrected. My guesstimate-o-meter says corrected is: Kato is ahead of Ventus. I'd need more coffee in my algorithm to do more.

    The Kahuna chuckles. Plenty of coffee ingested at Command Central. Wish you were here.
