Here is how the Mid- Ohio league came up with the weight of 4.0.
We took the heaviest mass produced custom figure and put it on the heaviest mass produced ttc . This left us around 3.8- 3.9. So we just rounded up to 4.0
I believe this was the same method used to establish the 3.2 or 3.3 as a standard.
I do sometimes wonder if there are guys in our league that have every single player on their team weighed up to 4.0
I like Reggies idea of a total team weight .
