I know you are a very experienced photographer and darkroom worker PKM, but just in case anyone else looks at this later on what he means is "even more dilute"! The standard dilution with Ilfostop is 1+19 and I use it myself at that concentration without a problem, as do zillions of other people.

It will be interesting to discover what the problem is caused by, as the whole process you described seems pretty optimal. Very good support from Ilford, as usual
