What does a positive total float mean?

Yes, positive total float is good. It's what project managers are hoping for. It is like a built in safety margin. It means you may delay an activity, accordingly, and not affect an activity constraint date or the project completion date. Zero total float tasks require attention.

What is supercritical activity?
