Retarding Ignition Timing

We run our timing locked at 38 degrees. I have been told that if I retard the timing a couple of degrees at the end of the track after going into high gear the car should pick up.

I have always heard that you increase the timing at higher RPM to assure that the spark plug fires early enough to keep up with the increased piston speed. Can someone explain to me why retarding the timing a couple of degrees at the end of the track would help pick the ET up?
