That's funny because I found the opposite to be true if it's a single bishop / knight endgame.

It will just take longer. A single five minute game a day over coffee will work, if that's all the time you have for.
No matter what you found, it has been statistically proved that a Bishop (against a Knight), and especially a Bishop pair is stronger than a Knight/Knight or Knight/Bishop .
Bishop pair is clear, of course, but I literally would look for a single knight/bishop ending (where I would have the knight), thinking it gave me the advantage. Maybe it was a placebo effect. Ha! Thanks again!
