No, I don't see another way and that is one of several reasons
why, although I [still] question the timing (no need to recycle
that discussion) I have been in favor of doing this, as an
experiment, from the beginning.  I am raising these issues now
in the hope that it will increase our sensitivity to the risks
and tradeoffs involved as we evaluate the experiment and what
information it might be useful to obtain to understand our
baseline before we start (the conversation between you and Brian
has, IMO, been very helpful that regards).
