Yes, I use 1:4 from the original concentrate. The 7 films in the tank were Tmax 400, but the other 2 were HP5 plus, which I did separately.

The recommended time was 6 1/2 mins at 20C, so I gave them 7 mins at 20C and they look OK altho not as much contrast as I like. However I haven't printed them yet. Yes I'd appreciate seeing your times for 1:7 if not too much bother!
