cheers--once you have got the renown system stabilised- so it's not going up and down like a yo-yo---you could then use it for something much more usefull---

having different patrol zones for differing renown levels--
have a system where by you keep an average expected renown figure for the period of the war (either taking into account the players start date--or by adding renown to the start renown figure)

if the player falls below this figure by a certain degree --he gets transfered-back to Wilm' in a type II for a while--simulate being assigned to a training role for couple of patrols--
or even brought up before a disciplinary council (as we know happenned late war) and has a 50/50 per cent chance of being shot for "cowardice" or similar

--

loads of stuff--could then be directly linked to the players renown total
you could even alter all the escorts in the game to a higher/lower crew rating according to the players renown--(gameplay job that rather than realism--if it could be done without major surgery--that'd be dynamic- from a purely gameplay point of view)



i dunno..
