You take two numbers and draw a very general conclusion. Look at other tables
and depths, which show a more significant superiority of std R=2 over std R=3.

Look at Tables 2 and 6. Vrfd R=3 solved almost the same number of positions as
std R=1 !!! Does it leave any room for doubt as for vrfd R=3's superiority over
std R=3 ?
