DP27 in Ilfotec LC29 ?

[btgc]

Along with my order received two bonus rolls of DP27 ISO400 film which is marked for processing as "Developing times Agfa ASP Surveillance Film or Rollei Retro 400S". Digitaltruth matches neither of them in LC29. What is Agfa ASP, I see only Aviphot line but also not with LC29.

Probably there's method how to figure out approximate times except developing short film strips and adjusting process?

UPD:
Just found RFFer SimonSawSunlight has developed 400S in LC29, but then there is another question - he has processed MF film while I have 135. Looking at DTruth I see some developers have same times for MF and 135 film, and some - different. In case of Rollei 400 and LC29 same times are listed for both formats, so is this enough to conclude I can use Simon's times for 135 film?

times should be equal, I never used different times for 120 / 135 with ilfotec. but be careful, I felt that it was quite easy to overdevelop the 400S. maybe 12-12.5 min are enough.

Thanks Simon, will try it at 1+19, although normally I use 1+29 as I prefer longer dev. times. Probably 15min. would work for 1+29 - would try if I decide to get more of this cheap film.

I forgot your warning and went for 13 minutes, yet weather has turned +30C and developer goes over 20C quickly, I think (even if I poured it at 19C, but tank weren't cooled). I got burnt highlights but rather on frames which were overexposed.

First time handling film on polyester base I were surprised how thin it is. It also likes to curl but after keeping rolled outwards overnight it straightened nicely.
