Congrats on the progress. One of my guitar teachers a while back said, "OK, now it's time to learn to read music."
I can see the benefit, but so far I've resisted because it's something I really don't want to do. I'd rather spend my guitar time learning things that I DO want to learn. So maybe, like you, in a few years I'll bite the bullet.
Again, well done. Forward progress is good progress.
