Back at it, what's the thought on tricep relaxation?

[Houngan]

Jumped back in and am pleasantly surprised how little I've lost over a year of not shooting. When I'm fresh I'm scoring roughly where I used to be. That said, I had to remember my sequence, and the last thing that I re-discovered was that if I relax my tricep at the top of my raise and keep it relaxed it helps immensely with left-right twitchiness. Is that something that is taught, am I backwards, fooling myself, etc?

Essentially when I reach the top of my raise and pause to align sights, check tensions, etc., I also relax my tricep so that I can visually see the muscle collapse on the outside of my upper arm. As I begin lowering it will try to re-engage but I keep some attention on it until I start to settle, where it doesn't seem to try to engage any further. My mental feeling at that point is that my hand is a single unit comprising my middle finger, palm, and wrist with my loose thumb and index floating above, and my shoulder which is moving the middle/palm unit into the hold.
