I'll own up to being one of those naysayers. However IIRC you did not do nearly as much work on your idea as @GreyOS has done. What you had presented was to create a sticky thread that you were only going to update for iOS 12 beta releases. You weren't going to do any of the calculations that are being shown here and you weren't planning on back dating it to cover previous iOS releases. I 100% support what @GreyOS is presenting here, but what you presented wasn't nearly as thought out and that's probably why I and others didn't like it.
Wow who would have thought beta drops would become a science. If I were at Apple, I would mix it up, just to drive everybody crazy. But only within a standard deviation.
