remaining project duration does not account for project lag when stages are missed for internal projects

[Lauren-Sittler]

This is definitely a problem in the "required technology readiness level" equation. The project lag is accounted for in the slope "expected technology readiness level progress" but not in the calculation for required technology readiness level. To fix the issue for this formula only you could add the project lag to the remaining project duration and put that sum in parentheses to be subtracted from the initial project duration. But a better question is - should we create a new variable to capture the corrected project duration or should we add the project lag directly into the project duration.

INTEGER(initial TRL + expected technology readiness level progress * (initial project duration - (remaining project duration + project lag)))

I think it makes more sense to include project lag into the investor expectations of TRL progress, because the actual progress is being compared against expected progress assuming that the maximum allowable number of stagegates are missed. I've added a comment to the parameter explaining the logic.
