Top Pages – entries linked to ‘days’?

I am using v13.1.1. I use the ‘Pages’ statistics page at least daily to monitor popularity of posted content. I have noticed that since a recent update, the ‘top pages’ table in the lower half of the page displays 10 entries when a ’10 days’ period is selected, 20 entries for ’20 days’ and 30 entries for ’30 days’.

Is this a bit of tidying up for aesthetic reasons or is maybe the wrong condition being used to determine how many posts/pages are included in the table? It means that some posts are excluded from the table despite receiving a fair number of hits.

Previously, when choosing a 10-day period, I might see 1, 2, 3 or more pages, each of 10 entries, according to how many post and pages were visited in the 10-day period. Being able to see entries further down the table is useful in monitoring new posts and pages. I now need to select a 1 month period to see further down the list and that of course is then cluttered with historic.

More worrying, is the fact that after selecting a longer period, 30-days for example, if I then return to 10 or 20 days, no entries are shown. The display simply says “No data to display”. In other words, after viewing the data for 30 days, you cannot then return to view the data for 10 or 20 days.

Also, for some time now the top 5 ‘trending pages’ shown in the graph above the table seems to bear no relation to the ‘top pages’ displayed in the table for the given period as it did in past versions. It seems to show some historic posts/pages.

Because of initial problems with the ‘Pages’ display from v13, I had spent some time rolled back to something like v12.9 of the plugin on my ‘live’ site and updated to v13.1 when I saw from my ‘staging’ site that these problems seemed to be resolved. I hope I am not going to need to roll back to an earlier version again in order to see the information I rely upon.
