Chessfun found that the 11-9 result was bogus and that Fritz was slower in these
games.

15-5 is not only the result of the 2 matches at the same time control but also
similiar to the results of other time control(there were results between 18-2
and 13-7).

Assuming that the 15-5 result is correct is the most logical assumption.

It is better to check all the games but I do not see a reason to assume that
something was wrong and if you have limited time to check it is logical to check
the extreme results and not the results in the middle.
