I don't see anything that shows demonstrated superiority of R=2 over R=3.  You
say to look at table 2 -- so do I.  It shows that R=2 gets one more correct
through ply 10, but takes over twice as long to do it.  I suggest that if R=3
were allowed to continue until R=2 is finished, that it would have found
significantly more than 1 solution in the mean time.

Table 6 has no node counts, so I don't know how much faster R=3 is than R=2.  It
gets 286 as opposed to 292.  Fine.  How much less time did it take to get it?

Maybe VR=3 is better than R=3.  The paper should allow me to draw this
conclusion.

A reason that I bring up the comparison between R=3 and R=2, is if you are
proving that R=3 is better than R=2, and you don't think that R=3 is better than
R=2, then maybe your other results are flawed.

You are writing a paper on some aspect of biological science, and your data is
suddenly implying that evolution doesn't take place.  Doesn't *that* seem worth
investigating?

Either you are on the verge of a serious breakthrough, or your testing process
is wrong.  You need to figure out which.
