Your online account shows your tier credit history by day. It's at aceplay.com on the first page after you log in then scroll down the page.
Since I'm sure you keep good records, this will allow you to calculate how much coin-in to earn each tier credit on the games you played.
At one time the higher card levels earned tier credits at a faster rate. Don't know if that's still true. Theo also affected the rate.

Does anyone have any idea as to how much coin-in is required to earn a Tier Credit at Arizona Charlies on 8/5 Bonus Poker? Says 10 Tier Credits to earn the first card level and 250 Tier Credits to earn Red Card (Top Tier). Slot club suppposedly won't tell and I'd like to have a basic idea going in.
