Try about 8 minutes at 72F if printing on graded silver papers, 12 minutes for printing on VC papers.
Pan F is a film that I use a lot in 120 film size but I develop it on reels with minimal agitation. For normal contrast scenes I develop with the 1:1:100 dilution for 15 minutes total, with agitation for 1.5 minutes at the beginning of development, and for 10 seconds every three minutes thereafter. This is a very nice combination for very sharp and almost grain free prints in sizes up to 16X20 from 6X9 negatives.
About ready to run the curves on that combo. I assume that there's not much difference between the 120 and the 35mm in that film (I have about 650' in 35mm for testing).
