I have no times, but in these situations what I do is to go to the
Massive Dev Chart. Sometimes they've got times in more developers (in this case it looks like they don't, though). If I can't find times for the developer I want to use, I start searching the chart for films with similar development times in the chemicals for which I
do have times and use those films as a basis for a guess. For instance, Kentmere 400 has times of 16:30 in ID-11 1+1 and 8:00 in Ilfotec HC 1+31. So looking for films with similar times in those developers, I find that Adox CHM 400 pushed to 800 and HP5+ pushed to 800 both have 16:30 times in ID-11 1+1; and FP4+ and Ilford Pan 100 (both at box speed) both have times of 8:00 in Ilfotec HC 1+31. If I wanted to develop in XTOL 1+1, I'd then look up those films, and get times of 14:15, 14:15, 10:00, and no listing, respectively. I'd tend to trust the 14:15 times more than the 10:00 time, since two films produced this result and because they were both fast films. Personally, I'd probably hedge my bets and try 13:00 or so as a first attempt, using a roll of non-critical shots to see how it goes.
Best of luck!
