Condor contains optimizations that automatically group jobs together. 
The grouping uses any attributes that appear in START expressions, which 
sometimes includes ImageSize. The rounding is to create fewer levels for 
the ImageSize variable and thus fewer groups.

You may want to use ImageSize_RAW.

STARTER_UPDATE_INTERVAL controls starter -> shadow update. 
SHADOW_QUEUE_UPDATE_INTERVAL (15min) controls shadow -> schedd update.

So you'll have to change both.
