I think there was some data that showed the majority of waste happened before a product got to a supermarket, and that switching to plant based/clean meat would be more efficient than cutting waste between shop and bin.
If 15% of the 11% gets wasted that seems less of priority than the original 89% that is lost, although maybe it would be a more tractable and neglected area to work on.
My comment was concerned with the impact of food waste on the number of animals suffering on factory farms. The report you cite seems to be discussing feed that is ‘wasted’ in the conversion process. But since this feed is likely to be mostly plants, improving the conversion ratio would probably not have a large effect on the number of animals on factory farms. (If anything, improving the conversion ratio might increase the number of factory farmed animals by reducing how much it costs to raise animals.)

On page 37 of this report it says, for poultry, 11% of feed energy gets converted into human food. https://www.wri.org/sites/default/files/wri13_report_4c_wrr_online.pdf
