How can I tell how long the Scheduler thinks a programmed run is going to take?

[Grady Boyce]

For example, if I set up a MUST RUN AFTER time, and I have told the Scheduler to do 200 images at 90 seconds.....where can I see what the Scheduler estimates the total footprint of time that will be allocated for this run, with it assuming the observatory parameters in the Scheduler Config file section 3 that I have set up for my observatory? Simple math says 200 at 90 seconds is 300 mins. BUT, what buffer does Scheduler add for all the other tasks necessary to complete the run?
