Step 1. Go to cod.tracker.gg
Step 2. Pull Last 7 Days worth of data for K/D, Damage per Game, Kills per Game, and Scores per Game.
Step 3. Using Excel, Calculate the Average and Standard Deviation of the data pulled in step 2
Step 4. Using Excel, Calculate how many standard deviations above the average each data point is. Why? This shows you how much better a data point is than the rest of the data in a set.
Step 5. Calculate each players Average Standard Deviation Above the Mean. Round to the nearest .1. NOTE: I am not weighing any of these values. A good K/D may get wiped out by a poor Score per Game. I would like to change this in the future since I think K/D is most important.
Step 6. Using Excel, assign a predetermined Rank to each Average Standard Deviation Above the Mean. Standard deviations start at -3 and go up to 3 by increments of .1. Ranks start at 71 and go up by increments of .5. For examaple a Std Dev of -3 is a rank of 71. If you have a Std Dev of 0 (this would be exactly average compared to everyone else) you get a rank of 86. This scale goes up to 101 but it is very unlikely anybody will ever get this high.
