For simplicity's sake I'll use round numbers. 50k MR = 67.5k VS = 120k Hilton (7.5k won't transfer). At 1.6cpp for MR it would effectively be .6667 cpp for Hilton.
Now that I'm doing the math, there are better numbers to transfer which will net Hilton at a lower price, e.g. 60k MR = 81k VS = 160k Hilton, effectively netting Hilton at 6cpp.
The lowest transfer for optimal rate would be 200k MR, which would net you 540k MR @ just under .6cpp Hilton.
