FX-37 development times?

[paulbarden]

I expect someone here has some experience with Crawley's FX-37 developer. I've done limited testing using it with T-max and Delta films, and find that when bracketing, anything exposure receiving more than about 1/2 stop more than rated speed looks seriously overdeveloped and getting blocked in the higher values. I'm basing my tests on what times I find on the Massive Dev Chart, but I found one reference to the fact that these times can result in significant overdevelopment.
Can anyone point me to any documentation of FX-37 development times, please?

Thanks,
Paul
