FP4 in Perceptol 1+3 dev. time ?

[gphoto120]

I shot several rolls of FP4 120 @ 80 and would like to know how long and what agitation method is suggested for Perceptol 1+3 dilution. I've searched the forum, but haven't found any actual time/temp agitation suggestions as a starting point. (Seems like there are many suggestions for HP5 .) I plan to shoot a couple of test rolls tomorrow, and would like to know where to start w/ development times etc.
Thanks for any suggestions!

21 minutes at 20C (68F) are the suggested starting times that Ilford have in their technical data. EI 80/100 seems about right as there is a slight loss of speed yield with Perceptol compared with ID-11 (D-76).
