So maybe a better solution is to remove the jitter routine , but set  
a default retrytime ?
It should give a similar degree of randomness,but be based on the  
jobs submittal time.
Thereby giving a greater chance of batching on failure.
but if the user wants to override the retry time then so be it.

I'm actually pleased how this is all working out, because without the  
batching , & based on last years figures,
 it could cost us an extra $10,000-15,000 dollars in non batched jobs.
