Damage score boards aren't calculating correctly

I went 7/1/5 on Anivia, and the Azir I faced in lane, who went 2/6/0 did 1,000 more damage dealt to champions than me according to the score board.

I HIGHLY doubt this is accurate, as the guy was getting stomped the whole game. There's been a few other games where the total damage dealt to champions looked suspicious, but I couldn't really prove it. With this game, I think it might actually be proof that since the last patch or two, the damage scoreboards have been inaccurate.

Also, a slight suggestion for the score boards after each game. Can we have it so that it shows the Graphs first, instead of the Table of stats? I never look at the table and always just end up clicking on the Graph tab anyway, so it'd be nice to just start at the Graphs if everyone else feels the same way.
