Repeat five to ten times to be sure which SumoBot's plow adjustment has the
advantage.
Adjust the plow of the SumoBot that appeared to lose more often, and repeat the
test.
When you are confident that one of your SumoBots has a winning plow
adjustment, try lots of different adjustments on the other SumoBot to find out if
there is any better adjustment that can make it the winner.
When you are satisfied with your winning SumoBot's plow, leave its adjustment
as-is, and tune the other SumoBot's plow until its chances of winning/losing are
close to even.
