If you have a super sprinter horse who is capable of clicking the following fractionals in a 10 furlongs race:
(Dash #1)
First furlong in :20 flat ------ (cumulative per fractional :20 flat)
Second furlong in :42 flat --- (cumulative per fractional :22 flat)
Third furlong in 1:06 flat ----- (cumulative per fractional: 24 flat)
Fourth furlong in 1:32 flat --- (cumulative per fractional: 26 flat)
Fifth furlong in 2:00 flat ----- (cumulative per fractional: 28 flat)
and you would try to race him clicking those very same fractionals but in opposite order, that is
(Dash #2)
First furlong in :28 flat ------ (cumulative per fractional :28 flat)
Second furlong in :54 flat --- (cumulative per fractional :26 flat)
Third furlong in 1:18 flat ----- (cumulative per fractional: 24 flat)
Fourth furlong in 1:40 flat --- (cumulative per fractional: 22 flat)
Fifth furlong in 2:00 flat ----- (cumulative per fractional: 20 flat)
How could the jockey calculate the real final time he can achieve in Dash #2, given the fact that now it seems imposible for this horse to click :22 flat and :20 flat during the last couple of furlongs of the race since now he is dealing with cumulative fatigue not encountered when he was racing in Dash #1?
Is there any developed formula for calculating times when running in opposite order?
For the purposes of this analysis the horse will always be running in lane number one and free of any traffic in both races.
