Ok so i didn't pay much attention to the ratings on the mangas on this site before as the two ratings were always fairly similar but i have now started noticing more mangas that have two different ratings on them.So i am wondering why does every manga here have two ratings what do they mean and which is more accurate?

Gonna need a mathematician/statistician? here, I think.. lol
But, I would take a guess that the blue Bayesian rating is, taking in the factor when a series did not get rated by enough users to give a reliable average. As there could be rating bombs or biased high rating etc..
If 1k users rated a series, the numbers are gonna be closer compared to say, 50 users. Something like that..
