I'd expect that.

When we tested radials on 40M we measured field strength, and that was 
pretty much the point where not much else could significantly change.

However, given the choice of four elevated radials at  six feet (equivalent 
perhaps of 24 feet height on 160, but who knows if it really scales or not) 
or 12-15 in the ground (and who knows if that also scales to 160), I'd use 
the buried or laid on earth radials.
