Stats, as in attack or defense stats have always been, and will remain a mystery.
I've done my own research using several test accounts for years.
I start A and B at the same time beginning to grow and develop both using the same vitamins.
Take great pains to grow them using the same units in each.
I've accumulated at least three dozen of these test accounts.
I have two factions housing 60 plus test accounts.
Despite my consistency in growing my "babies", one is ALWAYS larger than its twin.
For example, I have one let's call it Baboo, the other BayBay.
Baboo weights in at 50aa/100aa, and BayBay weighs in at 750aa/50bb.
i could go on with numerous other conflicting results, but I've learned to accept in THEGREELAND everything is bizarre, and inexplicable, as well as inconsistent and unreliable even in a CONTROLLED experiment.
