General Guide by Isthatok

Introduction

You may have come here wondering why your newly published guide has a 56% rating with only 1 vote, and how that is even possible.

Look no further - this guide has the answer!

The Bayesian Average

Mobafire uses a system called the Bayesian Average to calculate ratings for all of its guides. You can feel free to wiki it up if you'd like but I will summarize it in one sentence here:

Mobafire adds seven hidden votes at 50% each to every guide that has at least one vote.

Just type in the values you want and it will calculate your rating. Simple!

Why Bayesian Averages?

By doing this, new guides can't receive excessively high ratings. In turn this creates a more accurate representation of the rating distribution within Mobafire. This way, highly rated guides that have been around for a long time won't get outrated by a newly published guide that "got lucky" for awhile. As a guide receives more and more votes, the seven hidden votes bear less weight and the guide approaches its true rating.
