Actually, the division's OK, it's mlab.prctile which is borked. It
uses the length of the input array instead of its count to compute the
nb of valid data. The easiest workaround in your case is probably to
use:
>>> prctile((am/bm).compressed(), p=[5,25,50,75,95])

Great. Exact solution. I should have asked this last week :)
One simple method solves all the riddle. I had manually masked the MVCs using NaN's.
My guess is using compressed() masked arrays could be used with any of regularly defined numpy and scipy functions, right?
Thanks for the tip.
