I have had maybe three encounters with lone BFs at 20K+ co alt (with this beta patch) which ended with the BF109 disengaging or not resulting in a clear advantage for either as long as I maintained my alt and not give a guns opportunity during convergence.

Those encounters tended to be less aggressive with more separation, sort of plugging away untill someone makes an error so to speak, and if neither make a mistake the encounter can go on for some considerable time. I have no idea who the players were or their skill level.
