Let's not misrepresent things, Scott.
By my measures, only a single measure suggested support for your proposal -
https://cabforum.org/pipermail/public/2017-February/009487.html - but it
wasn't a hard blocker.
So we really are talking about painting a bikeshed, and we really should be
making decisions informed by data or for objective reasons, not just for

Except 398 days avoids that confusion. So the only remaining difference -
between 398 days and 400 - is purely aesthetic.

Explain to me what value that alignment provides, especially since that's
not a community involves with the CA/Browser Forum?
That's akin to making the argument that because red cars are known to be
faster, we should all own red cars. The premise it rests on is flawed, but
so too is the (il)logical conclusion.

I would think the fact that we still have a thread about 400 vs 398
suggests that some members very much are bent out of shape and pedantic on
Given that the Ballot was put forward at 398 days, precisely because you
offered no evidence as to the value or significance of 398 vs 400 (and have
still been unable to), is your suggestion that the appearances of this
community is best served by withdrawing the ballot to accommodate your
aesthetic desires? Don't you think that will have a greater impact as to
the negative appearances that you raise concern for?
