I don't think it's the OPPOSITE since the statement is in regard to winning or losing, it's just the fact that a win's a win is a win (winning's pretty well aligned with every point counting as far as I see it!). In regard to improvement a win is a pretty good step to take, ole Dom wouldn't say that winning by a mile doesn't matter
Overall, everyone can always continue to improve and adapt, because no one can ever be perfect... evidence: Wyndham still exists; solid evidence of the opposite of perfection.
