I'm not sure whether I should trust OP.GG anymore...

Yesterday, I checked OP.GG for Urgot builds, today I wanted to check GP playrate to see whther I should keep him on permaban and oh boy, what happened in 1 day...

Urgot jumped 12 places up :D Fiora jumped THIRTY-ONE places up (wth) Renekton jumped 3 places up :) Teemo jumped 6 places up :*D

Here's the screenshot;:

And as we got lower in ranks...

Jayce got 14 places down Garen fell 12 places down Akali jumped 12 places up Poppy jumped 18 places up Olaf fell 8 places down Trundle fell 14 places down

And this is just top lane... in 1 day.

Is it trustworthy?
