Ability to get hours expected in given window

In Classic LP we had an analytics report that we used to show hours expected to be consumed in a given period (week for example). It had started from a Task report. We could hit this single report with start & end date filters and get the work that 'should' be happening in this window.

Is there a way to query LP New for the same information? As I'm looking at the API, I'm only seeing filters for items based on their expected/target starts & finishes. I don't think this is what I'm looking for as reality might not be what we expected or targeted.

As a disclaimer, I'm not really an LP "user", I'm trying to extract information that our users are maintaining. My grasp of terminology and interconnections may be a little weak.
