I had the same problem with the deep bass rapidly = swinging the tuning hammer back as soon as I let go of it. I followed = the treatment with a pitch-raise. I did the upper first and then came = back down to the pins I had treated. The second time around I lowered the pitch first in case any CA had = made it down to the pins on the plate just below the tuning pins. There = was a definite feel of "breaking loose". I was worried about that but = the torque staid good for this, the second tuning. More loose pins have = turned up in the treble as well as a lot of false beats in the killer = octave. I tried leveling the strings below the pressure bar but that = didn't make much difference so I'll be looking at CAing the pins on the = bridge, maybe; removing the strings first from them might not fit their = budget. Has a lot of loose center pins too, flat and grooved hammers = etc. just have to convince them to buy a new piano.
