I'd say it's a bit different from that - you might or might not get better even in one sitting - but you don't necessarily stay the same - you don't have to play daily or too regularly either...sometimes not even touching the guitar for a week and then picking it up gives it such a freshness, and you have some crazy "unlimited" feeling where you stretch out a bit more instead of having played the same sh!t over and over for 30 days and just being too cluttered with it to really stretch out...that's the major downside of just practicing technique all day long and every day...is you just push yourself into a corner where you suck musically, you don't really go anywhere...

...go on a whim, try whatever strikes you at any moment - otherwise you're just another lame Yngwie, playing the same song 14,000 times and not really progressing one step///even though trying to play pretty freely and randomly can also set you into a repetitive rut...when that happens, don';t just sit there thinking of you to break it...do something else for a day or two, otherwise if you don't "progress" while still trying to every day, you wil remain a little "defeated", and giving yourself just a bit of time to relax, maybe a few days, maybe a week, then coming back, you'll have forgotten all about how you'd "plateaued"...

...analysis, analogy, these are all anal/reverse-mechanisms...don't stick your finger up your ass to forsee how your next session will come out ("setting goals")...prediction is the same as predetermined limitation...f@ck that...goals are alright for one thing - technique, but that is the same as having a goal of being another Yngwie or another whoever - only without goals can you actually achieve something...
