Anyone got a time and experience? I got 2 rolls for someone else to process, I process other people's stuff typically in Xtol replenished for B&W. While I process all my own Shanghai in Rodinal. Haven't found a GP3 time for Xtol replenished online.. only diluted. FP4+ is listed on massive dev chart @ 1+3 14 and 3/4 min for 20c, while GP3 has a time entered for 20 minutes at 1+3 and 20c. So I was thinking 9 min and 20 seconds for Xtol Replenished @ 20c possibly.
