Probably.

Ossified dampers, plus the fact that they are so well seated that the 
entire damper hits the side ridges at once, instead of that ever so slight 
lead of one end.

Just like that "ahhh" when you plop yourself in the recliner after a long 
day of damper regulation, all them bichords are sighing with relief.

It is a mistake to allow any mechanical object realize that you are in a hurry.
