The idea is of course, that I have a number of different options in
the way that it can be used, with very little effort.
From what I have seen, 90% is within the range of the commercial
units, but obviously not as high as can be achieved by a little more
attention to detail.

Yes, you're absolutely right and that's probably where I made my
error, I think that I was in too much of a hurry and I should have
started out with 15 or 20 min of total reflux before begining to run
off the spirit. That's my plan for the next batch. Thanks!
