If she is that good, answer the following questions....
1. Why is she using a SharePoint "disposable" saw? Most professionals use quality, re-sharpenable saws.
2. Why hasn't she got the timber supported on a proper saw horse?
3. Why does she need to mark the timber all the way round? A professional knows his cuts are straight.
4. Why does she Mark her timber more than once on each side? Isn't her saw sharp enough?
5. Why have a Doris doing it? We know they can't do anything in a straight line, (parallel parking etc).
oddly, all of the professional chippies that work with me, and a few cabinet makers, use throwaway hardpoint saws, the keep sharp much longer, a fw still use old fashioned saws that are sent away for sharpening, but only for the really classy work
oh and most hardpoint saws have a square built into them and 34 degrees
