Al Christman K3LC thoroughly sliced and diced the tradeoffs of number vs
length for given total wire investment is his Mar/Apr 2004 NCJ paper.
N6LF also has a lot to say.

I didn’t think it was the “shortening” OF the length of the radials that would
improve performance e.g. going from 10 125’ radials to 10 55’ radials (in the
case of a 55’ vertical); rather, it was the fact that 10x 125’ of wire could be
better employed to increase the number of radials, albeit resulting in shorter
radials, that decreases the ground loss (since most is nearer the base of the
vertical). If I’m correct, then shortening a given number of radials should
decrease loss or improve performance....
