Efke820IR Aura @ ISO1.6 dev time?

[stradibarrius]

I shot my first roll of Efke 820 Aura today at ISO 1.6 and used an 89B filter. I want to develop it in Rodinal 1+50 and the Massive Dev. chart say 14 min.

Does anyone here have experience with this film @ EV1.6 and Rodinal?

I use this film with an R72 filter. I always bracket my shots and find the correct EI is from EI 0.5 to EI 3 in full sun. (1 sec @ F11 to 1/8 sec @ F11). It is really hard to tell what will be the "correct" exposure even though I always shoot this film in Sunny 16 conditions. That said correct times for any developer is hard to suggest. For this reason I usually use Daifine as my developer for the standard 3+3 min.

P.S.
Massive Development Chart does give Rodinol times for the IR820 at EI 1.5.
