Why is that people cannot design software to ignore the ENL record
when the glider is not a motor glider? I am often irritated by having
to adjust my start time on OLC because it uses the noise level even
though I am not a motor glider.

When I asked OLC for ENL to be ignored I was asked "how shall we
determine your start of soaring flight". I responded "same as for
logs that have no ENL record". Nothing changed, it still uses ENL for
pure gliders.

OLC may use noise level to help determine when you are on tow.

On SeeYou, the noise level on my flights drops noticably when I retract
the gear, as you would expect. However, it also drops when I get off
tow. I suspect that the recorder can pick up the noise of the towplane.
Or the slower speed off tow reduces wind noise, though the noise level
on tow still is noticably higher than on a final glide flown at towing
speed.

I am looking at my most recent flight. When I got off tow, the noise
went from 60 to 40 on the y axis of the SeeYou noise graph (it went from
250 to 60 when I retracted the gear).
