...This is too much work for a forum post. I'm coming back to this later.
I think we probably get the gist enough to agree the general thrust. No need to make your brain explode ! Or am I just projecting?
You're right. I'm not going back and changing everything. The math is a little wrong though for the given situation. People get the point. I think combat illustrates it best, as does a repeatable roll: n*i*(1-(b^n))=z Let us suppose there is a party of 4 and a party of 8. Let us also suppose there is only one side on the die which gives us success. Therefore, b=0.95, i=multiplier, n=4or8. For a party of 4, overall combat effectiveness, z=0.742i For a party of 8, overall combat effectiveness, z=2.693i So a party of 8 is NOT merely two times stronger than a party of 4, but IS ACTUALLY 3.629 TIMES STRONGER THAN A PARTY OF 4.
