This is where you should be using your judgement, not mine. Why didn't 
doing the aforementioned reading, after the searching manual for 
"rerun", answer your questions? I don't know anything about this issue 
except what I've read there...

If you have a specific question about a fact or interpretation, then go 
right ahead and ask, but unless you're paying for a support and 
consultancy contract, nobody's going to go out of their way to do any 
work for you. :-)
