How to combine two parameters to get a single number?

Question

Mathematics

There are the number of days to complete the project and the number of hours to complete the project tasks. What formula can be used to obtain the percentage of completion of the project based on these two parameters?

There are thoughts that you can reduce both parameters to percentages:
1. d = (number of days until the deadline) / (total days for the project)
2. h = (remaining hours) / (total hours to complete)

Then use F score:
F = (2*d*h) / (d+h

)
1. d = 0.1 (deadline is still far away)
2. h = 0.9 (assignments are almost done)
But F score = 18%, which is not very satisfactory

Please direct me in which direction to think

PS in F score precision and recall should ideally be large, but the situation is different.
It's good when h is big and d is small

Answer 1

to get the project completion percentage

only the amount of work is needed: completed / total. With a stretch for reality, you can count the hours: spent / total.
The deadline is binary: enough time or not.
Well, or specify the model. For example, you can make a project “hot” when approaching a lack of time before a deadline. In addition to hours-per-tasks, count the actual tasks and their completion. Surely there will be discrepancies.
