If you are riding with a chain so dirty that you lose 15 watts then you don't deserve to be on a bike. A filthy, crap quality, too-short chain compared to a clean, quality, correct length chain is like saying you'll get better gas mileage if your car is not belching smoke and running on tires inflated to 15 psi. True but not relevant to the real world.
200w on flat land calculates out to 19.57mph.So where would one see this benefit materialize...my average power? My normalized power? My 2 min power?
Funny as I just replaced my chain about 2 weeks ago.200w on flat land calculates out to 19.57mph.
230w on flat land calculates out to 20.63mph
So you should see 1mph faster speeds!
Going from my gunkiest neglcted worn chain to a shiny new chain never gained me 1mph speeds.

I looked at my power curve and don't see any 30w jumps anywhere in the curve...should I demand a refund?
yeah where is the watt savings from spending an extra $10k to get the bike 3 lbs lighter? On the flat it might be 0 watts, heheALL of these studies should be taken, not for their actual watt promises, but for the relative importance of the part/position/psi, etc. Think about... if you add up all these "free watts"...
- 20 watts for aero wheels
- 25 watts for aero helmet
- 15 watts for aero frame
- 30 watts for proper/aero position
- 50 watts for low rolling resistance tires
- 8 watts for shaving
- 10 watts for XYZ bottom bracket
- 8 watts for XYZ derailleur pulleys
- 20 watts for chain...
