Jade Chokidai Prod Line - How does it work??

[Teluvian]

I have been hearing a lot of rules regarding the Jade Chokidai Prod line from various people, but I have so far been unable to find the official "rules" for this camp after searching the forums a good deal.

Here are the rules I have heard:
- You may choose to get in line behind the last person in line at any point, at which point you claim a time slot.
- You may AFK at the camp until your time slot, but if you go linkdead, you must be back within 20 minutes or you forfeit your spot in the line.
- You must engage the Chancellor within 2 minutes of his spawn time in your allocated timeslot or you forfeit your kill opportunity.

I have also recently heard these rules:
- You may receive NO help from another player unless they were waiting in line with you the entire time. If two people choose to help each other kill the Chancellor, they both fill up one slot in the line and must wait in line again to get a second kill.

I have many questions regarding all of this.

1.) If someone in the camp line goes linkdead and forfeits their spot, or if the person at the front of the line fails to engage or dies fighting the Chancellor, what happens to the line? Does the next person in line have a right to the kill as if they were in the timeslot all along or does he become FFA at that point?
2.) If you are waiting in line and someone in front of you drops out of the line for any reason, do you automatically move into their timeslot without knowing? Can you willingly keep the original time you signed up for no matter what happens to the line in front of you?
3.) If the rule stated above is true and you are not allowed to receive any help from a player who was not waiting with you in line the entire time (to prevent people that are unable to handle the camp from holding spots in line), then what happens if you are fully capable of soloing the Chancellor, but a friend or someone in line wants to help you anyway to speed things up? How does this work?
