yes, standard gear tiers have plausible and predicable bolster patterns. but I would expect the Devs to get at least that right before going wild. your data corroborates that notion. understandably, people reading your article and this thread are concerned about the "outlier" effects of non -standard/non-current gear and their relationship with the bolster mechanism. the data you provide makes "Sense," while observations, random inspecting have shown quite the opposite, outside of the standard tier.
Please do not take this as a criticism of your work. my disappoint is that work here does not go far enough, but thats my problem not yours.
