Machine Library in the Manufacture workspace of Fusion 360

I am looking for the right feedrate ration for fusion 360?

Machining time in Fusion 360 does not match actual machining time seen at the machine when running the CAM program

I’ve noticed that acceleration & deceleration in conjunction with the mysterious Jerk setting have much more impact on cycle time (especially on longer carves) than the feedrate.

It’s also worth noting that the free version of fusion 360 slows down rapid moves which also impact the estimated time.

I can play around with it until it matches. I’m just hoping that someone already has the info.
