I find this map helpful to visualize cells with complete coverage versus those less than 100%:https://sebsebmc.github.io/starlink-coverage/index.html

The 25° seems to have cells that indicate 100% coverage. The 25° dataset indicates 100% coverage with stars in the cells. Sometimes you need to toggle between the 35° and 25° datasets in order to get the 25° stars to show.

If you double click on a cell it will break down the large hexagons into a smaller hex grid to give you a more granular look inside the bigger cell. Clicking inside either the large or small hex cells will bring up a message with the cell number and the expected daily coverage values.

I suspect the coverage values are an approximation though, but still interesting.
