The problem here is that Date Range mode isn’t working right for points leagues.
The link you shared shows this as the date range:
However, it is only showing stats from April 17, not April 16 and April 17. It should be showing both, and the denominator in the P/IP calculation is including IP from April 16 and April 17.
To see how your team did on a given day, the Today’s Stats page is in fact the right place to look. For points leagues, I will surface IP and position player G on that page, since now that is imperative as it is the only place to see how your team did on a given a day.
On the Standings page, the Date Range function will be updated to be consistently inclusive of the starting date in a range for points leagues.
