Here is how it calculates
hours completed is the cumulative number of hours from lessons marked
as complete in your current grading period.
hours planned is the cumulative number of hours planned but not marked
as complete from today until the end of the period.
hours total is the sum of those two - the potential total hours for
the period.
not shown are hours which are incomplete, but in the past. These are
lost :(
When you bump lessons, the planned and total hours can increase,
particularly if you bump from the past (yesterdays lessons were lost,
but now are planned).
When you grade today's lessons, complete hours should rise, planned
hours decrease, and total remain constant.
When you grade yesterday's lessons, complete hours should rise,
planned hours remain constant, and total hours should rise.
Don't grade tomorrow's lessons.
There should be no impact on other students either. So I can't
explain everything you saw. I will check my tests and verify we have
test cases for this.
For Gregory, I see 54 hours complete, 56 planned right now
For Sophie, I see 59 hours complete, 20 planned right now
do these sound correct?
I can send you the exact dates, courses, and times if you can match
them up?
