I prefer to try it with movei but I am going to start with comparing R=3 with
smaller R.

Your result suggest that R=4 should be used in part of the cases even on the
hardware of today.

The only problem is to define the right cases in order to get the improvement
without getting the problems but I think that it is better to start by checking
if I can earn by adding 1 to R and only later check if I can earn by adding more
than it.
