YMMV but I barely used my BCP the first two months and received a hefty 3X cli regardless. I spent maybe 100 bucks each month on the BCP and the rest of my spending on the green card for MR points. I called in and asked about the 150.00 statement credit for spending, and while that offer wasn't available they did give me a 100.00 statement credit immediately which was great. Spending on the card doesn't really seem to factor into the CLI decision as much as it may seem. Amex does want financially stable customers who use their products though.
