So your TR Statement actually shows RCs (Reward Credits earned) and not TCs (Tier Credits). Now, generally speaking you earn 1 RC for 1 TC unless you play higher denomination games. On the February statement (sent for March), the double bonus was NOT factored in. So in your case, the 3,429 RCs should get you an additional 3,429 TC if those were the actual total number of TCs you earned playing. It also looks like if you played and reached the daily bonus benchmarks, those are doubled as well.
