It’s going to depend on whether or not you’ve got a click on every beat or every other beat.
If you’ve got a click on every beat, 180-200 BPM would be a good goal to get to.
If you’ve got a click on every other beat (like my practice tracks) cut that number in half, so 90-100 BPM.
It’s much more important to be able to play with control and good rhythm and tone though than to be able to play fast.
