This again?? I've developed, oh, a thousand or two rolls of color film for three minutes, fifteen seconds - sensitive, "critical" C41 - and, *NO* "unevenness".

Irving Penn developed all of his Tri-X in Ethol UFG for *three* to five minutes, and I don't see unevenness there either.

It might be a "good" idea to dilute and go for longer times, but I doubt that it is absolutely essential.
