Yes, endorsed. That should probably be mentioned explicitly. (e: added to the post)
(Technically neither of the technical definitions I gave applies here. And this is a case where you can’t maximize every percentile simultaneously—maximizing your 11th percentile returns means betting nothing, and maximizing your 10th percentile means betting everything. But yes, for a single bet, maximizing “probability of ending up richer than I would have, if I had bet a different amount but the result was the same” is probably the natural way to extend the concept to cases like this, and it means betting nothing in this case.)
