Matt has produced instructions that are given out with the boards. I'm
sure they could be refined, but most bridge players should be able to
cope intellectually with it.
As far as I can tell, everyone can understand and carry out the
procedure, but mistakes still slip in. I don't know if the mistakes are
from players who are new and unsure of the method, or slip-ups by those
of us who've done it a few times. Anyway, when we distribute the
results we often have to include notes of the form, "The record for Hand
12 is wrong. The HJ and D7 are swapped on Hand 15." (We can't change
the hand records as they're printed in advance, of course).

Probably. Of course, we already trust players not to sneak a look at
the hands while dealing etc, but it would be fairly easy to silently
memorise the positions of a few of the cards if you were doing all the
permutations yourself.

More likely, they'd just trade with each other at the same table. For
example, you could do the first permutation and pass it to your LHO for
stage 2.

The 4 piles from the first pass are stacked together, 1 on top of 2 on
top of 3 on top of 4, so it's just a deck of cards (with the cards in a
certain random order).
Hope this helps explain it. Having hand records is a big plus for our
little club. Time will tell if we get really experienced with the
system and start doing it flawlessly.
