Since I have a motorbase, I started to use the Ilford method too.
After twice a 2 min. neutral-to-alcalic fixer, 2 min. KHCA and then 5 times 2 min. washing (20°C +/- 2°C) with continuous agitation (motor base) to finish with 2 min ADOSTAB.
According to the Kodak Residual Silver Test, which is actually a 1+9 KRST solution,http://www.google.be/url?sa=t&rct=j&...zc_Ny619mPuJEw, and a Sodium Permanganate 1/1000 test to test the washing, it looks good, but I am absolutely aware that those tests are not conclusive, and good for my peace of mind, but better these than notting!
I process in King's Pyro-HD, which is superb, thank you Sandy!
BTW, is it true that Pyrocat processed negatives are less archival?
