N6LF has done quite a bit of actual testing of various in ground and
elevated radial systems. See: http://www.antennasbyn6lf.com/
K3LC has done extensive modeling of both in ground and elevated
radial systems: http://www2.gcc.edu/dept/elee/Faculty/Christman.htm
However, if the majority of your on/in ground radials are only 0.1 wave
you won't need many before the point of diminishing returns.

I understand that 120 radials is the golden standard. At what point is there
no significant improvement?
How much worse is 60 radials? How much worse is 24 radials (4 of 1/4 lambda
and 20 or 1/10 lambda)?
This may have been discussed in the past, but if there is any engineering
reference or field testing that has been done, I would like to know the results.
Thanks
