What I’m saying is that they are apparently using the wrong metrics for calculating skill. Individuals working in their spare time have managed to produce a fair skill balancer based on stats that works extremely well. ( https://forum.myrcon.com/showthread.php?7169-TrueBalancer-0-5-3-0 )
That sort of formula would be a good starting point for SD to use. They may be tracking the wrong information.
For example, SPM, or score per minute is a wonderful way to track someone’s skill with a particular merc. It’s a good overview of how good is X person at doing Y merc’s job. Does DB even log this sort of information even disparately ?
