Good topic. I think this discussion has some things in common with a thread I started about convection vape technique On-demand vape technique: to fire or not to fire?
I agree with @SBuyer that a constant temp is probably best. Control of the heat is probably best left in the hands of the user, either through draw speed or removal of the heat completely.
I think this is true only because the definition of a “really good hit” is probably really different across the population. S-curves and other heater control systems might work for some people but there’s probably too much variability across users to program heat release curves that work for everyone.
I think it’s an art to get the most out of your convection vape through your draw and knowing when to kill the heater.
