I tested this, and can confirm that Therion can indeed work at tiny,
tiny leg lengths. I produced a survey of 100'000 legs, of 1 mm length.
(I tried 1 million, but Loch just crashed!). And then at 0.1 mm length

It is below the resolution of the Loch graphics handling to render each
of the tiny lines correctly at that scale, but the overall rendering is
correct.

When fixing the points at the start and end of the survey, the overall
rendering is still correct, and the error is distributed correctly.

So basically, Therion can work at crazy small leg lengths, it does not
cause strange distortions. But that can take it beyond the capabilities
of the app being used to render the output.

Your error probably lies elsewhere.
