I know nothing about REBUY TOURNEYS...is this a "standard format"?

[MrGrob]

BUY IN: $50 / $10 REBUYS

$40 to the "POT" and $10 to a player's card?! After the REBUY period, if you knock someone out of the tourney, you get their player card. You get $10 for every player card you have at the end of the tourney.

Now, if the REBUY is $10, do you get the 1/5 the amount of chips you would for the $50 BUY IN?

I don't even know anything about how rebuys work, and this is a tourney being held at someone's house here. I just don't know how standard or weird it is, or what shadiness this format can bring etc.

Any ideas as to what this is like compared to the norm?

Thanks so much!
