Note that I do not think that there is a big difference in playing strength
between 112 and 110 but a beta tester got better result with 112 relative to 94
that is the same as the previous version that you tested and it was not the case
with 110(110 performed even worse than 94 but the results were not statistically
significant).

There were not played enough games with 110 to get significant results and the
tester already stop testing 110 because it was not important for me to know if
110 is better than 94 and it was enough for me to know that 112 is better than
the best tested version that was 94.
