Personal Handicaps

2025-04-28

How personal handicaps are calculated:

For each race in a rolling years worth of races (including Wednesday evenings but not short course) all the Portsmouth Yardstick corrected times are averaged and multiplied by 1.05 to give a cut off time any times greater than this value are discarded, because they are most likely the result of someone having a really bad race so is not representative and will unduly influence the handicaps.

Sample race:

Competitor	Corrected Time (s)
Ade	3000
Bob	3100
Carl	3200
Drew	3300
Earl	4000

For out sample race:

Cut off = (3000+3100+3200+3300+4000)*1.05/5 = 3320
Average of all results bellow the cut off is = (3000+3100+3200+3300)/4 = 3150
Audit = (competiors corrected time / Race Average) * 1000 rounded to the nearest whole number

Competitor	Audit
Ade	3000/3150*1000 = 952
Bob	3100/3150*1000 = 984
Carl	3200/3150*1000 = 1016
Drew	3300/3150*1000 = 1048
Earl	4000/3150*1000 = 1269

For each competitor the average of all there Audits is taken to determine their personal number, any audits greater than 1500 are not included in the average, to discard particularly bad races where a competitor has lost a lap due to being OCS or capsized a lot!

To use the personal handicap the formular is:

Personal correct time = PY corrected time / Personal handicap * 1000

Current personal handcap list as of: 2025-04-28

note a personal number of 0 doesn't mean your infinately fast (it just means we don't have enough data yet)
