I also have three small NFTs that track three different pools for about a month. Although, results I see are rather mixed (kind of no point to compare a small pool to a large one).
One more option to potentially better track those those pools would be to have us miners push pool operators to show good stats. A good start would be FlexPool stats page. My take is that if a given pool is not willing to update their stats page, there is no point to stick with such pool, and that should potentially be a good motivation for those pool operators. An ideal option would be if Chia UI would show the same stats (abbreviated), but seen from Chia network point of view, in the pool info.
