The most common method used is to raise the glider up off the tires
both main and tail.

This is the method shown in my Schleicher ASH 26 E manual, with the
front suspension point about where the fuselage dolly is and back point
just ahead of the tailwheel.

Often the original factory paperwork is lost and so too is the original
oscillation number, or the owner and his mechanic simply do not know
where to look in the paperwork for the number.

My factory measured number is on the original weight and balance sheet
(126 per minute). I've never measured it, but I'll try it next time I
assemble. It won't match the factory value because winglets were added
since then, but it will give me new baseline.

Or do not appreciate the
importance and helpfulness of this check.

My manual stresses this measurement after a hard landing. Sounds like a
good idea!
