U-Boat Crew Promotions Strategy Check
 

I've started this game twice now but never completed it yet. Third time's the charm I'm hoping.

A couple of things I want to verify as to U-Boat crew management...

The Key Skills by compartment, by priority:
Torpedo Rooms: Mechanical, Guns
Engine Room: Mechanical, Electric
Radio Room: Electric, Watch-keeping
Command Room: Mechanical, Watch-keeping, Electric
Watch:Watch-keeping, Mechanical, Guns
Guns:Guns
Damage Control:Mechanical - Depends on what's damaged

As a test, I took a save file and promoted the same Matrosmann Oberfreiter (3) to Bootsmannmaat (4) and chose each of the various specialties.
Here were my resulting skill increases

Promotion Elec Mech Guns Watch
Engines 20 20 00 00
Sensors 20 00 00 20
Command 10 20 00 20
Torpedo 00 20 20 00
Gunnery 00 10 20 10
Watch-K 00 10 10 20


As part of the testing I tried awarding several of the medals...
No medal changed ANY of the stats on the crewman's cards as far as I can tell. No increased efficiency, no additional experience. Course everyone is on shore-leave so morale is great.

Am I correct with what I've worked out? ARE medals of any benefit game-wise?

Medals are eye candy and have influence on renown or crew merit
