VG.35 uses same drag as VG.33, Sea Level speed was calculated based on power increase as starting point..... this gives us 494km/h at SL.
Then engine power curve was used to determine the altitude where 590km/h was achieved, if 494km/h was the SL speed.
VG.36 compared to VG.35 has new shallower, wider bath faired into a revised rear fuselage, basically aerodynamically refined.

Rate of Climb:

Calculated from VG.33 climb speed but what it would be if we only changed the power curve and but extra weight.
VG.36 compared to VG.35 is more aerodynamically refined.
