I don't have the time here - I think that it was something around 9 minutes - but I can tell you how I calculated it. I took a film for which I had times in D:76 1:1 and Refinal, Afga's version of D-76 (Rodinal would work too) and worked out a conversion factor, applying it to the Refinal time that I had for the APX100. Thus, if Plus-X took 9 minutes in D-76 1:1 and 6 minutes in Refinal, and APX100 takes 5 minutes in Refinal, you would multiply the 5 minutes by 1.5 (9/6) to get 7.5 minutes. This should put you in the ball-park and, as I said, you could use Rodinal times if you don't have Refinal times, although they might not work quite as well.
