Shifting for fuel economy with the i4 (K24A4-i-VTEC)

I've had a hard time finding a good resource that explains the best shifting points for highest fuel economy using this engine under various loads, so here is a hypothetical set of test conditions (substitute your own specs if you have some relevant numbers):

Load: '05 Accord LX, 5M (unloaded vehicle weight: 3177lbs) %gear% 0 - 35: " 0 - 45: " 0 - 55: "

If you know of any resource where this kind of info is posted, great!

If you've done some experimenting on your own: Love to hear it.
