Default Any downside to lowering cruise RPM?

After a couple test passes today to make sure the car is ready for the season, I decided to mess around with cruise RPM for no other reason than to see how the car responds. I dropped from 4200 to 3600 and noticed an almost 2 mph increase with nearly a full second less stop time to run 9.90. Datalogger shows an equally flat cruise RPM at the lower RPM and 20 mph less wheel speed when coming off the stop. The car was very good all year with the higher cruise setting, but I'm liking the little extra MPH and shorter stop time. Anyone experience a downside to this?
