one month on and my best has only moved to 1min 15 secs but I can see my general times are around 1min 25 as opposed to the 1min 30secs.

Mostly right and I feel there is not a lot left for me if it's moving the mouse and hitting the right button that is holdingmy times where they are.

Definitely finding more reference points around the fretboard and getting better at coming back from the 12th fret rather than counting up the string
