Huh? The way you wrote that makes no sense whatsoever, but I will take a swipe at it anyway...
Many PDT folks who have been around for a while could back me up on this: Y'all remember when we used to do CLT-FAY? We used to depart about the same time as a mainline Dutch Oven (Fokker 100) that was going to FAY as well. We beat them almost every time. Why? We went low and direct, more or less. They flew way the heck up over RDU to get higher and burn less gas. The moral of the story? On shorter stage lengths cruise speed is not the sole determinant of block time. The same is still true today, LGA-PHL and PHL-ABE come to mind. The block times are the same. The speed only makes a difference on longer routes.
Oh yeah, the other night up in the northeast, when all the jets were canceling flights due to the high winds, the dashes were still safely (albeit not comfortably!) transporting their passengers to and from PHL and LGA. The 36 knot crosswind limitation is nice, and so is the big rudder!
