So, this expression is trying to do a "best fit" of the jobs to the 
partitionable slots, in order to minimize fragmentation.  In your case, 
if you want to put the selection of the machines completely in the users 
hands, I would change this to

NEGOTIATOR_PRE_JOB_RANK = (RemoteOwner =?= Undefined)

So that the system sorts unclaimed slots first, but punts the rest of 
the sorting to your job rank.
