Yes, but the vario doesn't "know" that unless you have multiple switches
on the flap detents. Also, how does the vario "know", from increasing
"g" that a pitch up was caused by elevator travel or by the change in
angle of attack due to the vertical component of the thermal? Do we
also need stick movement measuring equipment?

Perhaps it can tell the attitude of the glider didn't change by using
the gyro info, indicating the upward acceleration was caused by a
thermal. If the attitude pitched up - stick thermal.

Using the actual change in attitude may be much better than the stick
movement.
