According to the Steinway manual the hammershank flange for teflon should
measure
3 - 6 grams.  I just happened to have a teflon action on the bench and I
took off
note #64.  It measured four swings and the flange measured 3 grams to the guage.
At 6-7 swings the flange would be considerably looser than 3 grams.

This would support the view that 6-7 swings indicates a very free flange.
