Why still no dive acceleration difference?

Whether 4-blade Naca16 outperforms 3-blade Naca16 above Vmax is NOT confirmed, the confirmed fact is that 3-blade naca16=3-blade ClarkY and 4-blade ClarkY=3-blade ClarkY.

Even assume 4-blade naca16 has no advantage above Vmax at all, that is to say, P47P51 is equipped with German old narrow chord Gottingen airfoil, P47 still has around 20% efficiency advantage(300-400HP) above Vmax, ie 0.7Mach.

So simply assuming 85% for all CSP when above Vmax is totally unacceptable for high speed tactic il2 players.
