That seems bassackward. If you do the same throw headwind vs tailwind it seems that lower spin:speed ratio makes the disc more understable, which is opposite of what you want.
Well I'm not sure exactly what your saying, so I'll state that - lowering the RPM of the disc causes it to flip less. It flies more stable to OS. The headwind has the opposite effect, causing the disc to fly more understable due to the increased air speed (disc v + wind v).
Think of this as a finesse throw where you want to maintain a straight to turning flight with a controlled finish in a headwind. Not for a wide open headwind shot where you'd be silly not to throw something OS.
'Remove some spin to counter the wind'
Tailwind has the opposite effect. More rpm is needed to maintain a straight flight.
Is that backwards? Are you in NZ, maybe?
