Then do the opposite: with your existing bike and existing PM,
1) collect data while riding up a hill while shifting normally; then
2) repeat on the same hill while shifting like mad; then
3) repeat on the same hill while keeping the bike in one single gear.
Then see how much the cadence/torque/power relationships vary across your three runs.
