The increase from 195 to 208 suggests an improvement in prop efficiency on
the order of 20% or so.
If the old prop was a miserable 85% (it should be in the 87 to 91 range)
then the new prop would be up around 102% or so in efficiency.
(208-195)/195=.103 or about a 10% improvement
I've been told that props are usually 80% efficient - a 10% improvement would bring that to 88% efficient.
