I believe this was brought up in the How's the Game? But now I can't find it, so I will ask here:

Will backtags that extend into the current month count for the AC check? I can understand why they wouldn't if they were few in number, but if you had a lot, shouldn't that count for something? At least if you were currently on the list for needs-more-tags.

I know determining a quantity/quality would raise a whole 'nother issue, but those tags do take time. I don't want it to be an excuse, but a fallback in case things happen.
