I did some test matches with Yace recently although I am not completely sure I
can interpret the results correctly using above terminology.

At least for Yace there wasn't any significant difference in strength between
R=2 and R=3 at all it seems.

As I remember the only slight tendency was that lower R values might be better
at slower time controls.

I am not so familiar with this stuff, so to be exact I tested null_h=4 against
default and null_l=4 against default at slower and faster time control.
