There are a number of factors in play here. Typically, if there aer 
available resources, you'll probably not even notice a delay. I don't 
know of any document that lays out the factors, maybe -

If you're searching around for info, key terms are: negotiation cycle, 
claim recycling, claim reuse, reschedule

At a high level, the condor_negotiator periodically starts a negotiation 
cycle that hands out resource claims to condor_schedds, who run jobs on 
the claims and re-use them between negotiation cycles. Also, when a new 
job is submitted a reschedule request is sent to the negotiator, which 
may be ignored if it comes in too near to the end of the last cycle (20s 
iirc, by default).
