Thanks for the follow up, and an excellent return on card spend!
My card spend is primarily focused on Hyatt Points and United Miles. Redeeming with Hyatt, I get around 4 cents per point, equivalent to 4% back on spend, not including bonuses. With United, I aim for around 2 cents per mile. However, for the past 9 months, I've received consecutive offers on my United branded chase card (Quest) for 5-10k bonus miles for $5k in spend in 3 months. In addition, these offers have stacked with a 3x bonus miles offer for groceries, restaurants and gas. That's the same bonus received for airfare on United, which is the only other thing I use the card for. So for at least the past 9 months I've received 5-6 miles per dollar of card spend, or about 10-12% back on spend based on the redemption value of the miles.
