Given ESPOIR uses extracted intensities - has it been
tested/how good is it on single crystal HKL data 
(0% overlap) in suggesting a starting model?
Am mainly thinking in terms of datasets with poor intensity, 
ambigious spacegroup, etc - but it should work by default
on good quality data(?).

Surely if ESPOIR/Monte Carlo methods can do a good job with 
intensities extracted from powder data, it should be able to do
at least as well on single crystal data(?)
