Hi Francesco, on the molded Supra, for zoom speed it was actually -.5 degrees in reflex and not quite flat bottomed.
Cruise was 2 degrees camber, and penetration was with .5 degrees camber so there was a 1 degree reflex difference between fast flying vs zoom.
On the Maxa, there is also about a 1mm flap setting difference between fast horizontal flying ( penetration mode) and zoom speed. Penetration is with wing flat bottomed and adding an extra mm reflex to this would yield better performance for zoom speeds.
However, I think adding a bit more might be better as Kyle experienced because of the droop nose. The added reflex beyond optimal causes the wing to fly at just slightly less than "no lift" = negative lift which keeps the fuse more inline with the airflow. Just my hunch based on other planes I have tested
