For instance, a big red flag on the bacon that went from 90% pork to 89% pork. That sounds like a rounding error to me. Certainly not worthy of calling out.
Then tomato sauce (a preserved product) moving from raw tomato to preserved tomato getting called out when by all accounts, I can't imagine why that would matter. The product is after all, a preserved tomato product. Benefit of the doubt I'd just call it a recipe change. It may be better now. Just because it's different doesn't make it worse.
Finally the Chicken Tikka going from 26% marinated chicken to 14% cooked marinated chicken. That line item includes the marinade in both cases - which evaporates during cooking. How much of that is lost water and fat? How much of that was just the marinade cooking off?
Why is "deflation" just as red as "inflation" and "shitflation" - isn't that what you want? Lower prices?
I'm confused, I think this is a pretty weak presentation all around.
It would be really interesting to learn the magnitude of these effects but the way it's presented here it's hard to learn anything.
