Esports percentage pick/ban rate

Hi, I've already sent this topic to Riot support and they redirected me here. Anyways, I'm huge fan of LoL and Esports, I watch every competition in every region, but I have problem with pick and ban ratios that you display in champ select. I've done few charts (just for me and fun) while watching pro games and I just wanted to share them with you (chart that I'll be sending is for Worlds group stage). I'm not sure if anyone from Riot will see this, but I hope that someone will. Thank you
