Hey @tripartist1 I suspect you're using the beta 1 release. We had an issue causing a Z0.0 move at each layer when the coasting was enabled and therefore did a fix and made a beta 2 release.
On that version the print time and material usage is within expected range.
No coasting

Coasting enabled

Can you check to see if you're problem still persists in the 5.9 beta 2? If so, make a project file that showcases the issue and share it with the report.
There is now an option under help that creates the support package with the logs as a 3mf
