The report states (for example) that if the average person reuses a plastic bag 40% of the time, you would need to reuse a cotton bag 173 times just to equal the environmental impact. It doesn't matter what the actual reuse rate is to establish the comparison, only this: Is it more likely the average person reuses 40% of their plastic bags one time, or is it more likely the average person reuses their cloth bag 173 times? (in other words, groceries 1/week for over 3 years)?
From my own experience, I still use cloth bags from several years ago, and I go shopping 2+ times per week. I don't know what the average usage is though.
Also keep in mind, this study was done in the UK. That 40% reuse number seems a bit high for here. In all my trips to the grocery store I have seen people bring their own plastic bags only a handful of times.
