Issue 3-84, Heroes on the Mass Scale

[PaoloRosso]

I've been using Mass Combat in my current DF campaign and was interested in using the Tactical Strength calculations in 3-84 for stat-ing my adventurers. The example given in the article gives the PC a TS of 61. A Heavy Infantry element has a TS of 4...what am I missing that explains why a single character could be 15x more effective than an element of 10 warriors? I see the austerity factor for a gritty/realistic campaign is x0.1, which would change my PC to a TS of 6.1. Is the assumption in the Mass Combat supplement that all units are using this factor?
