What are you high on ?
You are basically contradicting your own statement by saying 1:1, and then saying 2RPs are 1rs.
Also, while yes it does, a lot of entry level to mid tier cards are beating the RR or almost at par.
SBI Cashback, ICICI apay via iShop (4% iCash & 1% as Apay balance), Axis atlas etc.
Plus, you are basically paying 4.13% upfront which is not worth the 0.9% extra you get on DCB imo
