If you tuned the middle string first, it has been hit roughly twice as much
as one of the outside strings, and roughly three times as much as the other
since you tuned it. It could very well be out of tune with the rest of the
piano, but you tuned the outsides to it as you pounded it out, so it's more
likely to be in tune with one of the outside strings than the two outside
strings are to be tuned to each other. 

That's what this other will say.
