See Yield Calculations for a discussion of the differences between ROI and TWR yields.

Still, the runners noticed the difference: In their time trials, they paced themselves differentlyâand ran about 1% slowerâfor every 3.5 ounces of lead added per shoe. The researchers calculated that elite runners wearing shoes 3.5 ounces lighter than normal could potentially run a marathon about 57 seconds faster.
