Hi Sandy!

In the following you say:

"Pyrocat-HD can also be used as a two-bath developer with excellent sharpness. For this I recommend a 1:10 dilution of both Parts A and B, with solution temperatures at 75F.

1. Water bath for three minutes. Not necessary for most films but I recommend the water bath for Fuji Acros, Tmax-100, Delta 100, and most fine grain films of ASA 100 or less.

2. Six minutes in Part A, with two inversions at the beginning, and two inversions at the 1/4, 1/2 and 3/4 points of development.

3. Pour our Solution A and pour in Solution B. No rinse between. Initial agitation two or thee inversions, then two or three inversions at the 1/4, 12 and 3/4 points of development.

4. Pour out B, pour in water and leave for five minutes.

The purpose of the relatively long time in B and the final water bath is to allow developer exhaustion for maximum adjacency effects."

In step three you mention agitation times at initial pour, 1/4, 12 and 3/4 points but I can't seem to find the time it should be in Solution B. Same as A?

Looks like he has stated in #26 that for normal film speed B would be 4 minutes.
