Of course, high speed stability is a function of throwing speed.
this depends a lot on the disc.
i would say low speed overstability is more a function of throwing speed than high speed for MOST discs.
seems only the 8-10 fastest drivers on the market are really dependent upon speed for their high speed, but nose angle comes into play greatly on these.
wind tends to exaggerate nose angles. e.g. a headwind pushes nose down drives more nose down and makes nose up drives more nose up.
removing wind and assuming clean power in the 200-450' range and a nose down throw, these are some molds that will fly with the same high speed stability:
