Please explain in more detail. Not clear what you mean by "optimum is going to be very slippery." Are you saying that the benefit of slower flight and therefore tighter radius circles outweigh the losses from the higher sink rate? Not trying to be a smart alec, I seriously want to learn from you more experienced guys. thank you.

Best climb isn't achieved at minimum sink. Usually (90%), it pays (in climb) to fly slower than (load factor corrected) minimum sink speed. The optimum is going to be very slippery -- it depends as much on the thermal characteristics, turbulence, etc. as it does on glider performance. It's this sort of abstract, complicated, multivariable, analog "computing" that humans can still do better than machines (with enough practice). Enjoy it while it lasts!
