You can object, but your equation does not account for the size of your bet which is the key here. If your bet is $10 you need to win these blinds way more often than if your bet is only $5. If you are winning these blinds only 56% of the time (or 55.55556% if your going to argue accuracy, plus or minus half a percent with regards to a poker game is not worth correcting) with a $10 bet you are actually loosing money, where as a $5 bet with the same win rate breaks even. You need to win about 71% of the time with a $10 bet to break even.
