Why is my top float path not the critical path? I have a float path that read -164 Total Float with a fnl constraint and completion date of Apr. 6, 2021. That is a lower Float path than the next path that is -177 with and a fnl constraint of Apr. 25, 2023 but has the check marks for critical path and longesth paths. Why is the first one ranked above the 2nd one in the Float Path Order? I really like the float path order chart but don't quite understand it. My guess is that your first "problem" is more of a problem than your 2nd problem and thus more pressing? Or perhaps, because there are mixed calendars, the various float though the activities add up to more negative float.
