Not sure if rates are figured out exactly partly cause I don't think alot of the stuffs caps are all that well known. It does seem to have something similar to crafting in being so many over helps your HQ rate so much. Though in a much different manner. Like alot less to get capped rate and highest HQ rate is way more for synergy then crafting. Distribution between the HQs seems to be the same as for crafting.
Actual craft skills have no bearing other than if you are able to attempt the synth
