What is does “last week to date” mean in the Team Admin portal?

Last week to date compares point totals from the current week to the previous week, limited to the days of the week that have passed so far.

Weekly competitions start on Monday. So, for example, when checking player progress on a Tuesday, a Team Admin will see only the Activity Points that player has earned on Monday and Tuesday thus far. 

"Last Week to Date" will show the Team Admin how many Activity Points that player earned on Monday and Tuesday of the previous week.

This provides a more accurate point of comparison from week to week.
