I am dabbling in handicapping and am trying to relate courses by distance class etc. Can anyone help me with a formula for the best way to "average" times for races at a distance and track. The sample size varies greatly and I think mode is probably the way to go but need a formula to take care of skew. Mode=3(median)-2(mean) leaves a little to be desired.
Or am I completely on the wrong "track".

Any advice greatly appreciated
