3:53 seems a bit long, considering Fuji recommend about 3:40 or 3:45 for the last fifth of their rated capacity.

I understood the 3:15 time to be for continuous agitation.If considering a 10% reduction for rotative processing, that would become 3:02 first pass and 3:29 for the second pass, but I don't consider the 10% reduction when I make E-6 and I see that also compard does not take this into account.
