Oh FUN. I think I now get it. Using B1 appears to be much more timing
sensitive than B8 on the A300CS that I have access to.

Specifically, in my setup my first attempt to use B1 almost always fails a
couple of times (but the algorithm then simply retries and eventually
succeeds). I almost never see failures with B8.

The way I tested things initially I saw the failures and didn't retry but
assumed (looking at the trace of what the Aeris software does, which
ALWAYS uses B8) that I should try B8... and that worked. And then when I
tried B1 again at a later point, it once again failed and I figured they
had removed this. Turns out that I'm wrong.

This is excellent news. I can rip out a big chunk of the new code that I
wrote :-)
