And this is how we know.
One avatar with Street brawler and the other with kick boxer standing 1.69 meters apart.
We took turns standing in stance directly facing each other and going thru the numbers in order, this is what we found;
Street brawler would hit the other avatar with numbers 4, 5, 7 and 11 and in turn kick-boxer struck home with all 12 hits. Then we swapped huds and the same hits and misses occurred. (street brawler missed most of the time and kick boxer hit every time) Then we both attached street brawler and we both hit only with numbers 4, 5, 7 and 11. Then we both put on kick boxer and hit each other consecutively with all 12 strikes. This was all done in stance at 1.69 meters part directly facing each other.
Can some one else confirm this by testing street brawler themselves?
