Repeat with 10 inversions.

Repeat with 20 inversions.
As I said above, Ilford doesn't mention a waiting time.
But in "The Film Developing Cookbook" Anchell & Troop state that although the process has been published without the wait time elsewhere (possibly referring to Ilford), this is wrong and the tank should be left to stand for 5 minutes between each fill and set of inversions.

It can't hurt.
