Troy Grady has some videos I’ve watched that really helped to articulate what I realized. He has a method for sale. I haven’t purchased it, but someone on the Telecaster Forum said it was good.If you can articulate that now there will probably be a dozen kids singing you praises. The only way I could go faster was to start incorporating hammer ons and pull offs. I’m sure there are probably better ways Than that because each of those techniques adds its own tonal flavor. I did notice if I was going faster I had less thumb on the neck.
