I think, it can be expected that there is no big difference at small depth, when one looks at possible lines. It depends on the exact implementation of the numm move algorithm. One possible scheme of searched lines with R=3 could be: depth line 2 move null (qsearch) 3 move null (qsearch) 4 move null (qsearch) 5 move null (qsearch) 6 move null (search with depth 1) move etc. So, even with an aggressive nullmove, at depth 3 the effective R is equal 1 only.
