The pic attached is a sample of one I made.
Using technical data from rcdb.com and other similar sources, I made a ranking system using Microsoft Excel that gives a sort of objective total score for a roller coaster and rank them all based on that total score. I also take those scores and combine them based on the parks in which they are located and rank the parks as a whole. I can explain in further detail how the scores are calculated if asked, but basically it comes from bell curves from six separate sets of technical data, which are opening date, track height, track length, top speed, number of inversions, and ride comfort (the ride comfort is based directly off of the speed stat and the type of roller coaster).
The primary goal with doing this is to create a legitimate roller coaster ranking system that is 100% objective with no influence from polls, opinions, or anything else subjective.
Let me know what you think, but please don't tear my head off if you think it sucks.
