I've set it ours to be twice the length of time of max walltime, so (if I'm 
understanding correctly) a job of that length can be planned to fit in at a 
point when a job also of that size which had just started will finish.

So ours is (amongst others): bf_window=23040,bf_resolution=600

All the best,
Chris
