This page is based on statistics calculus and is a culmination of much discussion and tweaking among several mekoramaforum.com members. It was about determining how levels could be ranked monthly in a relevant way.
Next to a period of researches, a calculus has been suggested and adopted (thanks to RichardFu!). This has led to publish each month statistics and charts regarding levels likes and ratings.
Since then some more work has been made to publish a tool to help each and everyone to do that on his own. This is the reason for this page.
Choose a date range to find out an order of preference among the levels published on the forum. From that you can text filter result or reorder them on a specific column. You can even mark the levels you've done as a reminder, that will be stored in your browser.
