Default Lift - Newton/Bernoulli ratio...

Does anyone have any figures and references for about what ratio lift is
produced by Newton's Laws and Bernoulli's Laws?

I appreciate this is not a static figure - but say a yer average C-172,
or perhaps a 737.

I would hazard a semi-educated guess that lift is *primarily* produced
by angle of attack (or deflection if you like) - Newton's Laws - and by
a much lesser degree by Bernoulli's Law. I would guess that Bernoulli's
principle might create 20% of the lift a wing generates. A friend
believes it would be much lesser - about 5%.
