LP compensation

I just had to play a 42 min game in order to earn 2LP. That is just frustrating and unfair. Either the prior game total of 98LP should have rounded up or I should have had that win count as the first in my series. Otherwise this is just the system being horribly obnoxious. Given that I have been earning ~22LP per match, that means I just played an entire game for 1/11 of the rewards I should have earned. This is by no means the first time I have been stupidly close to a series and had to play for a ridiculously small amount of LP (see My running ranked match history here).
