I have tried it out - and have seen differences. One in particular was

135
on the wheel and 141 on the cradle. That's not a huge difference, but
enough to warrant a closer look, so consistency in technique will help
avoid false alarms.

Suggest instead of opinion - just use the MM for the glider. e.g. ASG29 MM
para
3.2 gives the support points. MFG data sheet at build gives original
frequency,
MM7.1 requires annual check, MM7.2 requires it after hard landing, gives
tolerance.

Good clear info from Schleicher, which all ties together nicely imho.

And a very nice app from Clyde, thanks. Like a lot of great ideas it seems
obvious
now but you thought of it.
