A card room have daily tournaments.
For this card room, if player arrive at the card room before level 2 started, player will receive a free buy-in to the tournament (weekday), and half-price discount on his first buy-in on weekend.
Now, the guarantee for this tournament is 20000, the buy-in is 200+20 for 10k chip, the one-time add-on is 200+20 for 20k chip.

Add-on happened during a break before level 10 (around 500/1000 100 ante)
The tournament speed-up after level 10 (blind go up quicker)
It is very often that the re-buy and add-on exceed the guarantee…….
The problem that I m having is whether should I rebuy? And whether should I add-on?

Scenario 1：total pay-out is minimum guarantee, Ievel 10, I have 10k in chip, should I add-on?
Scenario 2：total pay-out is minimum guarantee, Ievel 10, I have 50k in chip, should I add-on?
Scenario3: total pay-out exceeds minimum guarantee, I got knockout of the tournament, should I rebuy and add-on?
Scenario3: total pay-out exceeds minimum guarantee, I have 20k in chip, should I add-on?
