Ferguson's Rules to BR Management

[OSUGreg1983]

I'm slightly confused by Ferguson's rules on when to exit a game when it gets too expensive.

He says you cannot buy into any game exceeding 5% of your bankroll (I get that obv). But, he says you must leave the game when the money on the table represents more than 10% of your total bankroll. Does this mean that if you win a few pots and gain a larger stack at the table that you must leave when YOUR OWN stack reaches 10% of your total bankroll.......or does he mean you must leave when the entire table's cumulative chip stacks add up to more than 10% of your total bankroll?

I feel like this is probably a stupid question, but its not clicking in my brain. Thanks for the help.
