serious question regarding folgernal

Since almost all the search links for folgernal referred back to the

same original posting, I'm left wondering whether the 30-minute

processing time includes agitation.

Would it make a significant difference if agitation were 10 sec/min

or 20 sec/2 min? I have some Bergger 200 rollfilm (which I've

discovered is decidedly not the beautiful emulsion that their 4x5 is)

that I'm willing to play with, but the thought of sitting there,

babysitting my tank to do agitation every 50 seconds is a bit much.

At least with 1:50 between agitations I can read something, work on

the Great American Novel about the angst of alternative process

photography and so on.

Thanks,
