My first guess would be that maybe you’re digging in too much in order for the attack to have the tone you want? I know I do that. I’m always trying to get a good solid attack with less pick and less movement. But I tend to go back to old habits if I don’t play enough.
If you watch a real pro play, it almost looks like they're not even really playing what you're hearing - there's so little hand movement.
After watching players like Nuno, you realize it's about economy of motion.. There's no wasted effort.
He uses the exact amount of motion/effort needed to accomplish the lick. No more, no less.
Over the years I've try to eliminate the extraneous hand motion out of my playing, and it really does help.
ymmv
Nice. It’s hard to change your technique when you’ve been playing a long time. I’m learning some flat picking bluegrass stuff right now that has a lot of economy picking in it. It kicked my butt for awhile, but economy picking does allow for much more efficient movement, which equals a smoother sound and less muscle tension in the hand. It’s difficult to get there when you wanna alternate pick everything, though. Lol
Yngwie’s right hand is one of the most compelling techniques in all of rock guitar. It’s such efficient movement it appears almost as if his right hand is hardly moving at all.
I think that might be part of it... seems I'm using more force on the initial strikes, then I relax a bit through the run. I've really focused on that and I see an improvement in the last few days. Gotta make it last though. haha
. Probably enough for my life time. 
The carpet trick! I’ve done that for decades to nearly every every pick I have....I use “Cool Picks”…. 1mm black. Slight bigger than the Jazz III. When I found out about them a decade or so ago, I bought a shit load since you couldn’t get them easily. I easily had like 300 of them…but they last a long time when you rub them in the carpet and re-sharpen the edges. I must have 200+ left.
. I was looking at Lynch pick the other day and he almost holds to the front of the pick and uses the rear half to contact the strings. So bizarre. Marty too..how the hell does he pick with that gimpy hand.
FWIW, I took a small piece of bubble wrap (the kind with the small bubbles) and put that in a microphone clip and then wedged my phone in that so it would have a light grip on it. Then positioned the mic stand for the phone to be about belly height and angled downward just so. Then I just play standing up with a strap. I just walk up to the camera and once everything is positioned it works pretty good.
I thought about not being able to make a change, but I’m actively working on it. The only thing I don’t like is that it’s making me think then playing, vs letting it flow naturally. I’m sure this will go away, but I’m happy with the results so far. I do realize this may end up fruitless, but it’s fun trying to advance.
