Actually, you can usually get a 100 cent flat piano at 440 pitch within 
3-4 passes and never go above 442 to do it. I suppose you can call that 
overpull, but thats not what folks normally mean when they use the term.

That said... even sticking to 440 as a limit.... a couple passes more 
and it will stay there.  Theory is one thing, reality is another.  Take 
the elections for example..... grin... no I guess I dont want to go 
there after all.
