I have come up with a new dinghy handicap formula is it fair that a boat does a lap less.
Formula for calculating handicaps even if slower boats do a lap less with correction for boat doing a lap less
CHT= corrected handicap time
AT= actual time in seconds
ADJ.PY=boats handicap
NLC=number of laps boat has completed
NF= most number of laps done by any boat during the race.
CHT=((((1000*AT)/ADJ.PY)/NLC)*NF)/(NLC/NF)
boat 1
using the formula for mirror doing 5 laps in a race where faster boats do 6 laps
my formula
CHT=((((1000*1500)/1385)/5)*6)/(5/6) = 1559.567
old formula
CHT=((((1000*1500)/1385)/5)*6)=1299.639
Boat 2
using the formula for a laser doing 6 laps in a race where slower boats do 5 laps
my formula
CHT=((((1000*1695)/1087)/6)*6)/(6/6) = 1559.338
old formula
CHT=((((1000*1695)/1087)/6)*6) = 1559.338
boat 2 wins which is fairer as they did more laps but only just which means handicaps still play a part in the race
