You can’t say that it is an advantage, simply because you never know when you crack a block, so it could be just when you were just starting to ramp up or when you almost ramped down after you left (if you decided to do so in a shorter term). And you may not hit any blocks while your ramp up is at its highest these days if you don’t stay for a long time. 
The whole point of this system is to deter people from doing just that (pool hopping). Once you are fully ramped up you could do things like take down a machine for cleaning and put it back up next day and hardly notice a dent in profit loss.
Also the frequency of the payments doesn't mean its paying less. If something, its paying little bit more (less tx).
You could get payments every day or every month, Does it matter if the sum of everyday payments in a month is equal to a monthly pay?
