No offense intended Terry, but you cannot say with this match which program is
the best.
The result of this match is 51.63% in favor of Fritz.
I don't have the typical margin of error for 306 games, but I know that for 400
games it is +/-2.5% (80% confidence) and +/-2.1% (70% confidence).
So even if you got this 51.63% with a 400 games match, you couldn't say which
program won because 51.63% is between 47.5% and 52.5% (80% confidence). You
couldn't even say Fritz is better with 70% confidence.
That's the problem with chess matches results... You have to apply some
statistic formulas and sometimes you discover that the match does not say which
is best...
