The deviation is slightly greater and the ratio slightly less in C 
than in A. It would be natural to suppose that surface friction and 
irregularities would produce a decrease in velocity which increased at 
a greater rate than the velocity itself, and in that case the ratio in C 
would be greater than in A, as was actually found by Berson from 
the manned-balloon observations.
