The point is that not posting the results of styles that do not make it
give less information.

The point is that people can give wrong impression by the following steps:

1)Trying many styles.
2)Choosing the style that perform the best based on results that does not have
to be the best style because of statistical error.
3)posting only the result of the style that made the best result.

I am sure that you do not try to do it on purpose and you look at the games and
not only in the results but it is still possible that you may get wrong
impression because few games with good results may not expose an important
weakness.

Sarah probably means to say that posting results without bias is posting all the
results that you have including results of the styles that do not make it.
