A tight turn after release from tow is also a good way for the data analyst
to determine when the glider released and therefore the release altitude.

Not if you want *me * to certify a height gain it doesn't.
The gain is the gain to the maximum altitude from the previous lowest
point after release.
A circle proves nothing about eactly where the release was and what
altitude it was at. Note the first EW barograph had provision for a
release detector.
In the absence of that, notch the trace.
