[I got second thoughts about this, so I cancelled my earlier post on the 
news reader, but maybe it is still there on the web site. Disregard what 
I wrote. Sorry for any confusion]

Using +C works correctly on a render without saved radiosity data, as 
radiosity calculations restart again for the not-rendered part of the 
image and only for that part. So, what you may be seeing is not a 
complete re-calculation but only for the not-rendered region? That would 
be correct.

 From your post I assume you do not save/read radiosity data? For very 
long renders using sslt in particular I think that would be necessary. 
with the pretrace value at 1 for the reading sessions as Clipka wrote.
