> Sampling shouldn't be feared

Well I would say the opposite, sampling should absolutely be feared. In a lot of case sampling is not an issue, home page, or popular page but in others, including checkout pages, , product pages, and low visibility pages, sampling can make massive difference. When working with sampled data you should always keep it in mind

I think his point is that those pages likely shouldn't be sampled (if they're truly low visibility and therefore don't have much traffic).

But would that happen on a per-page level or a per-site level? I think probably the latter, in which case the data is going to be a lot less useful where arguably it's most important.
