TP means treatpoints for maybankard user.
For Maybank2 American express card, every RM1 you spend can get 5 Treatpoints.
Every 12500 Treatpoints can redeem for RM50 voucher.
So 12500 treatpoints = 12500 / 5 = RM2500 of spending
RM50 / RM2500 = 2%
Conclusion is 5x TP give u additional 2% Cashback in other forms of reward.

https://forum.lowyat.net/topic/2048731EDIT :
I saw that u are using plusmiles card too, plusmiles card give u additional CB.
For every RM1 = 1 points u spend on plusmiles on selected tolls, you get RM10 back, or another 1% Rebate
If your monthly usage is above RM100, you give 5% rebate but no accumulated points.
Hence MBB2 amex + plusmiles can get from 8% - 12% cashback monthly.

Okay, I kind of get the whole idea now. So now the question, how do I get the rebate? Instant or every month when the CC statement comes to me?
I hardly get to spend more than RM100 since I only go through Batu Tiga Toll, which is the Subang <> Shah Alam, RM2.20/day on weekday. Weekend go out with gf, never use any selected tolls also.
