The flight

What the tracklog shows, and which crossings scored.

Crossed the start cylinder boundary 29 times. The scored start is the latest crossing from which the flight still makes its best run along the course — re-starting supersedes an earlier start, while simply flying back through the cylinder later in the task changes nothing.

Track data cleaning

174 of 9082 GPS fixes (1.9%) carried an implausible altitude and were repaired before analysis — flagged by vertical-speed limits (no barometric channel to cross-check). Positions and times are never altered. How data cleaning works
