Pitch Raising to A440.......Or Not?

[Farrell]

I do a lot of pitch raises. Many are significant - 30 cents to 150 cents.
These are pianos whose owner do not have the need of exactly A440. The last
few I have raised to A441 or A442 - figuring this will help speed stability
at A440. I have not heard of others doing this. So I must be doing something
wrong!  ;-)

Waddaya'll think of such a thing to do?
