Schedules, assumptions and every run are kept against your account.
At least 8 characters.
A project holds a block model, its assumptions, and the history of every schedule run against it.
Leave blank to use the built-in reference case.
Every choice below has a default already selected. The defaults are the agreed assumptions, and each alternative is offered only where it is genuinely defensible.
Grouped by what they affect. Anything marked fixed is not offered as a choice, and says why.
