hmm, little strange, but these are actual set values for the Repair modules as you can see in the Modules.xml file ^^
just a note: If you have problems in the middle difficulty, Try to buy some mercenaries at trade stations
and i don't think that repairman stacks with system expert.
PS: It seems the Hidden stashes Thread got deleted or something, atleast it was archived:
