You really can improve your list.
- Remove Intel Grand Slam points (totally biased), or give 2-3 points.
- Give x2 factor (or more) to Big Events Rating. or multiplier by 20 like: 1.10 rating = 220 points, 0.95 = 180 points [(minus 20 points (2*1.0-x)] (Individual Matters a lot)
- Give Atleast 2 points for Major Finalist (2nd place).
- Add 0.5 points for each HLTV EVP.
- Reverse Top 20 Should have 0.75 factor, or have a new formula like: [(ReversePoints/NumberofAppearences)+(NumberofAppearences*2.5)]
Like i said, your list is still the best list i've ever seen, but it's not perfect yet.
