good day all, we seem to be having a non-fair fairshare with 
our fairshare setup. i have this:

FSINTERVAL        48:00:00 
FSDEPTH               4
FSDECAY               0.80
FSPOLICY        DEDICATEDPS

my queue looks like this:

now, if i check start on jobs 910 and 912 i get:

[root at moldyn queue]# showstart 910
job 910 requires 64 procs for 12:00:00
Earliest start in          1:35:52 on Mon Mar 10 14:47:43
Earliest completion in    13:35:52 on Tue Mar 11 02:47:43
Best Partition: DEFAULT

[root at moldyn queue]# showstart 912
job 912 requires 32 procs for 12:00:00
Earliest start in         13:35:52 on Tue Mar 11 02:47:43
Earliest completion in  1:01:35:52 on Tue Mar 11 14:47:43
Best Partition: DEFAULT

which seems incorrect. i would expect fairshare to promote
912 ahead of 910. how have i got this messed up? this is

Maui version 3.2.6p19

thanks for any help!
