Right Flying at 2500rpm instead of 2400rpm, gets you almost four extra mph. I'd also want to figure the increase in fuel consumption. If extra speed makes you do an extra fuel stop, you've lost all advantage of the greater speed. In many cross country flights, I've increased my total speed by slowing down to 90 or 85 or so and, by getting better fuel economy, I've been able to safely bypass a fuel stop. Taking all this into account adds to the mental brain-all-involved-and-active aspect of flying that I love. Ed
