Wanyenulak in your postin #35 I believe you have a math error by using the cog teeth alone rather than as a denominator in the gear ratio. When calculating cadence the chain ring matters as well and needs to be expressed as gear ratio not just cogset teeth. So were i have an average 11% change in gear ratio and you have an average of 9% change; that's a 2% difference. That is, your cadence changes from, say, 100 to 90 and mine changes 2% more from 100 to 88.
What i actually did was use the gear calculator and set it to include speed; and then slide the cadence bar around to simulate a shift. I think i have that right.
