I think a test like that compares apple and oranges. Put side by side a Futura and an Isonic of identical volume and the difference in early planing would be very small, if any.
My old Mike Lab 77 wide, 270 long and probably 135L or so for 6Kg weight is one of the earliest things planing around here, and it is neither a slalom nor a freeride board nor a formula. What I mean is: build light with a lot of volume add some length and you get an early planing machine that picks up at 7-9knots depending on sail size. Fun is going to be relative: if the winds picks up no light wind machine is going to be "fun"!
