Hi Tom,

Thank you for your quick answer. We are using dev-764, you go too fast! :-)

I didn't supply any models directly, just two hhr files, so I guess the
first five models from each hhr file are used? Add to this that the
space group has an enantiomorph (and it seems to me that both are tested
even if use_all_plausible_sg is set to False) and that I requested
prerefining. For the time being is not sending more than ~ 170 jobs at a
time, which should be fine.

I will let you know if newer versions behave differently.

Best regards,
