[Analytics]Bulk Moved Expirations and Renewal Rates

We ran a utility to extend everyone's membership by four months due to COVID.

My Analytics dashboards track Renewal Rate with [Total Renewed Membership Count] / [Total Membership Count]

This has generally worked wonders, but when I look at last year, March, April, May, and June are all around 100% renewal, which would be super, and July, August, September, and October are all well below expected rates. I realize now that adding time to those memberships was making them count as a renewal; so all 2,520 memberships I had expiring in April got "renewed". I don't feel confident in these July-October numbers which dip down to 20%, considering our normal renewal rate is around 65%.
