I doubt that.

How long since the last tuning that it was 60 cents flat?

It sounds to me like the piano did extremely well being only five 
cents flat a year after a 60 cent pitch raise. It's also no surprise 
that the unisons were rough, and it wasn't the vertical hitches that 
did it. More likely, it was strings rendering through the bridge 
over time after you had done the pitch raise and left the building.
