I think the 1 XLR at a time payouts you see at the moment are actually accumulated rewards paid 1 XLR at a time, but I may be wrong.

Thus: 0.9 XLR per block is currently distributed 45% to PoW miners and 45% to MN holders, thus for MN 0.9x0.45/701 (there are about 701 MN holders now). So each block adds a bit up to your reward which is paid out when it reaches 1 XLR

And when PoS starts its first phase, the MN will get say 1x0.45/701 instead for each block.
