Yeah I think a standard formula like "For such and such manufacturer X part increases/decreases Y stat by Z percentage" would be the most useful if indeed it's that simple. Any research you have pertaining to individual parts rather than manufacturers in general would be especially helpful considering you only really care about min/maxing when you get to the higher levels in ultimate vault hunter mode and you are trying to farm/wear only the best (note: at the very least but mostly legendary) gear.
