Right, I think we're in agreement here, but your restating it makes me
think you may believe we're in disagreement?

I'm not sure I understand this point. I just tried to explain why it'd be
problematic, which is something we discussed quite a bit several years ago,
with feedback from WebTrust in particular on this point about the
misalignment between days and calendrical events. Root programs took that
feedback into consideration, and that's why the approach I mentioned
specifically exists to reduce the risk of compliance issues. It's unclear
if you believe those concerns to be unfounded or unnecessary, or if I just
didn't communicate this well.
