Index of performance:
Handicapping formula:
Measure width across back wheels of all entrants
Compare entrants’ width against widest (Benchmark) entry
arrive at index factor of entry X against widest entry by dividing entrant x with by benchmark.
That index factor is applied to entry X’s time.For example:
John’s 911 is 55.6mm across the back tires. Being the widest competitor this is the BENCHMARK dimension for this race (stage)
My Triumph Herald is 40mm across back tires
Divide Triumph width by Porsche width for INDEX Factor.
Index factor in this case is .71942
Both make 40 laps or rally track
911 completes 40 laps in 360 seconds
Herald completes 40 laps in 430 seconds
Handicap is 430 X ..71942
Handicapped time is 309.35 sec.
I think in the interest of a varied grid, the Index of performance will be weighted equally to overall performance points-wise So, conceivably one could winn overall, AND Index of performance for double points!
Can anyone point me towards the method used to score the Targa Florio rally earlier this year ?For the second time in my life I wish I knew how to use a spreadsheet.
