Pallet fork and balance staff replacement usually get me enough amplitude to barely reach tolerance...

OMG, so you first dismantle the entire movement, clean everything in an ultrasound bath, then re-assemble with 'perfect' lubrications, then measure too low amplitudes and afterwards you must change one piece/component after the other (although you do not see any signs of wear) until you get acceptable amplitudes? Is that what you have to do?
Barely reach tolerances? What are the amplitude tolerances (H- and V- positions) after a service? I am curious to know these numbers (for my 32xx watches, two need a repair).
Bas, many thanks for all these information and explications, very interesting and much appreciated.
