Does a K-cup deliver the same amount of caffeine regardless of cup size?

I’ve been drinking coffee regularly since I was a child. If I had my “druthers” I’d be drinking a custom blend of coffee beans, slow roasted to dark perfection and brewed for four minutes in a French press. However, since that is neither affordable or practical at this time, I’ve come to appreciate and depend upon the trusty Keurig my son bought for my caffeine delivery system.

Also, my cardiologist has suggested that I limit my caffeine intake to 2–3 cups per day.

The machine has three cup sizes, but the K-cups are the same. Using the same brand and roast, will I get the same amount of caffeine from a 10 ounce cup as I would from a 6 ounce?

Humor welcome!
