One data point ...
I have been working my way through some Fuji HR-T green sensitive x-ray film and have settled on shooting it around EI 50 and developing about 3:30 in HC110 1+63 ("Dilution H"). For comparison, using that dilution on regular photo films times fall in the eight to fifteen minute range. Since I'm tray developing 8x10, I use steady agitation. (And of course, one can develop by inspection under a deep red safelight, though I find that not as simple as it sounds!)
In general it seems workable to burn enough exposure to get shadow detail then pull development, using a dilute developer to spread out the process time-wise.
