This business of going back a week later to fine tune a piano after a pitch raise is a load of old codswollop! Get it over and done with in one session. Any piano that is tuned, will need a tuning a week later anyway if you are going to be that critical. In brief, and by no means the whole procedure, my formula for pitch raising is to overpull 7 Hz for every semi-tone the piano is under pitch; e.g. if the pitch is at 400Hz, overpull by 14Hz to 454Hz. This should ruffle a few feathers. Gradually lower the amount of overpull as you go along. Works like magic, except of course on wooden framed jobs, which defy all the laws of sanity.
