To clarify, Masternodes earn 50% of all mining rewards, that includes both PoS and PoW.

PoW are currently at 200 Mag. 100 Mag goes to masternode winner each block. PoS would vary depending on staking which is computed in coin-day units x 7% / 365. So basically at the moment these PoS rewards are quite low but could later on earn more than PoW blocks when wallets are staking more coins. (a 5-day old 100K stash would reward as much as a PoW block).

Since the network is pretty new, staking occurs with small amounts and these are the rewards you get. When your MN is selected as winner you have a 50/50 chance to be rewarded with PoW or PoS. Both types would reset your rank.

Hope this clarifies.
