Never understood the rationale for snap release (edit: I meant why it's better). Why not maintain random or almost sweep (full release) and just adjust the release interval by prolonging it?

If you do it properly by uncocking the LW hard & fast with the right shoulder, you will answer your own question of why it's better! Here's how: Throw the bent right arm and the entire club down plane with the right shoulder.

Deliberately delaying uncocking requires hand/wrist/arm tension and you can't let go the tension fast enough, so the uncocking is slower. Forearms, wrists, and hands must be tension free from the top.
