Hi,

The problem was the profile test failing as suggested by Wladek and Lothar 
(thanks to both, for continuous teaching since grad school). I was using a 
profile fitting radius of 25 (not the default 10), so that's why I assumed 
profile fitting was not the problem. But now, I have played with the profile 
fitting radius (PFR), and below are the numbers.

PFR    Compl%  Compl% (high res bin)
25      81     63
50      96     80
60      98     86

And with hindsight, it was very embarrassing to find in my log file "count of 
observations deleted due to zero sigma or profile test", which tells me the 
problem. And again, because mosflm was giving me 100% complete datasets, it had 
to be a scalepack-specific implementation.

Interestingly, at a PFR of 50, a single profile covers almost a fourth of the 
image. Any input on that one?

Try to increase profile fitting radius.

>So before I lose it because of HKL2000, I have two questions, and I'd
appreciate any answers to either:

than blind region at higher res., overlaps, overloads, and "not enough many
frames")?

Another explanation for incompleteness could be due to crystal packing that
results in an asymmetric diffraction pattern.  The discrepancy between
HKL2000 and mosflm maybe a result of the resolution cutoff, however, this is
only a speculation.
