That is the sort of methodical practice I don't do so much these days, but it can be useful. I've seen mention of the 'flying fingers' somewhere. Makes sense if you want to build speed. I also did Artistworks for a while with Paul Gilbert and having him check out your playing is quite something.
I notice on some of the exercises your right pinkie flicks out. I don't imaging it's an issue, but shows that fingers do work together. My right hand is very weak due to nerve damage, but I can still finger pick some tunes. Maybe some exercises would help build the strength.
