Yes, I am thinking along the same lines: considering whether this would approximate the amount of classroom time per week, plus the amount of time allotted for homework outside of class.

Do you happen to know (or can you find out): were these existing lessons?
- Or was the material from the regular lesson plan recorded into videos as the pandemic lockdowns and school closings
...extended?
- Or was material cobbled together on the fly, to fill time?
- Or...?

Knowing this may yield an understanding of the likelihood of these lesson plans and materials being reused in the future (or leveraged for some parts to be used again). The likelihood of revisiting some or all of the materials may indicate how helpful it may be to other/future students, to have an amount of work designated as "Day1," "Day2," "Day3," "Day4," "Day5" for each Week. This may also reveal the teacher's level of openness to feedback on modifying/improving the lesson delivery, including providing time estimates.

On the other hand, many students/families are witnessing "differentiated task demands" being used in their schools as a technique to close achievement gaps, performance gaps, excellence gaps. This involves requiring top students to complete more complex and time-consuming work in order to earn the same grade as other students. The concept was introduced in an old thread years ago (2014) and was analyzed/discussed in this post. With a bit of peer-to-peer discussion with other classmates, or among parents, one might begin to confirm whether other children in the same class are being assigned the same work, or different work.
