| The claude gordon method (A systematic approach to daily practice) advocates the use of pedal notes - he recommends using the same fingering descending from bottom F# as you would use descending from the octave above. In reality pedals are not real harmonics and need careful coordination of hearing with embouchure and air. when you get below pedal C it opens up a bit and the notes slot more easily all the way down to F.
