I won't argue with your POH! Does it give the speeds on both takeoffs?

1.2 Vs for both conditions, premature raising of the nose or raising it to
an excessive angle will result in a delayed takeoff. Normal takeoffs are
with 10degree flap settings. At MAX GW, accelerate to 65-70mph, slight back
pressure to let the airplane fly itself off the ground. Accelerate to normal
climb. Enroute climb speed is 115mph, gets the nose down for visibility and
air cooling into the engine and better forward speed.

Short Field no obstacle, 25degree flap settings and lift off at the same
65-70mph at MAX GW. The text does state that with no obstacle, accelerate to
best rate (Vy) 105mph

Short Field With an obstacle, 25 degree flap, lift off at lowest possible
airspeed and accelerate in ground effect to 95mph, (Vx), climb at 95mph
until the obstacle is cleared, then accelerate to 105mph (Vy)

I should add that this is from the 1973 PA-32-300, fixed gear, fat wings.
