Response to asa

Sal, single roll in old Nikor SS tank. I don't use a pre soak. Tap it on sucessive bottom corners to release bubbles. One minute of continuous agitation initially (the first 15 seconds the tank is inverted GENTLY), then 5 seconds every 30 seconds. The tank is picked up and gently rotated 30-45 degrees 5 times in 5 seconds using gentle wrist action. I put it down gently, and turn it 90 degrees so it's rotated on a different axis on every agitation. The agitation is GENTLE don't stop or start abruptly.
