I’m with Uwe on this. Recently I’ve been using Ilford Delta 3200 but have had very low contrast negs (using Ilford’s recommended times). My probe tells me grade 5 is up to 2 grades too low, but I find if I shorten the exposure by up to 2 stops & let it develop for the full 3 mins (Multigrade developer 1:9 and Ilford Classic fibre) I actually get very acceptable prints.
Good luck!
Michael
