I'm usually quite good at keeping total reported balances below $1K (prepaying a few days before statements are generated), and have no other loan products then 7 credit/charge cards.

What's "acceptable" for churning purposes in terms of total number of credit cards and total amount of credit limit showing on the bureau for >100K income?

How many credit cards can one have on the bureau and still be able to churn?
How much total credit limit can one have on the bureau and still be able to churn?
