Excellent, ando - thanks for sharing! The more independent and varied data we record the more effective and reliable the information will be. I have expanded the spreadsheet to now include contributor, tire pressure (which has an effect on rolling resistance), and total rim/tire weight to aid in comparing. If you happen to recall your tire pressures (and estimated rpm at that speed), ando, that would be great but if not that's OK.
And if anyone can find the unknown data in the yellow cells it would be appreciated. I can't find it anywhere, but it would be best to have a complete data set if possible.
And although we only have a(n) N=2, already some interesting comparisons. Fascinating that the M40i has better Hwy efficiency, but only with a lot more data sets will any potential conclusions be able to be considered.
Thanks again for contributing to this, ando!
