Indi AGA has no sync to Amiga vertical blanking, so getting 50 Hz is moot point. I've done some experiments. For example managed to get 50.014 Hz refresh, but then scroll tearing was more noticeable than for frequencies between 55 and 60 Hz. This is because for 50.014 one gets around 75 frames in sync, then one frame is repeated twice, which is easily detected by human eyes and brain. For 55 Hz every fifth (or sixth) frame is repeated, which surprisingly gives better overall experience.
