I'm pretty sure you pick the "proof" that suits you.
I don't remeber which months that were hidden or open, but I do remember that one of the tightest first votes was an "open" month. Could it have been August?
Either way, it's not for you OR me to decide.
Personally I like that we go between the two. That way all can be happy at least part of the time. But that's just my opinion.
Edit: Checked and August sure was visible! https://www.mobileread.com/forums/sho...d.php?t=185641
