When you say 1.05 to 2.05 difference between classes..at what distance are you meaning?...class difference by time will vary at each distance

to simplify it you could work..per mile ..which simplifies the whole process somewhat.

for instance on the flat..at 5f a class difference between class D and C might be say 0.45 seconds...if you then convert that to a per mile difference..its 0.72 seconds.

to convert a time from 5f to a "per mile" you just divide the distance 5 by 8..so each time you bring a 5f time difference to per mile you always divide by 0.625

at 6f its 6/8..ie divide by 0.75

by bringing everything to per mile you can compare any distance time with any other distance and see straight away which is the fastest when actually compiling your speed figures

alternatively you can treat each different distance separately..but bear in mind that the time diffence between class C & D at 2 miles will be less than it is at 3 miles.
