Any best practice on how to represent player progress stat in a game?

I'm making a musical game where user should recognize notes and get faster at note reading. I'm in the designing process and I get quite stuck on the designing of the player progress on the level representation.

Here is what I got so far:

Try 1

Using percentage is great for progress and knowing where to train, but does not represent a speed.

Other try:

Try 2

Using speed is great but on the other side, does not give much information to the player if he's great or not (is 10 BPM great or not?)

So I'm looking for best practice in design UI assets or creative ideas to show player progress. Any ideas?
