The Verituner never makes double tunings "mandatory". This is entirely up to
you and a matter of personal preference and experience.

Pitch raises are handled through the Coarse Tuning View, which is a needle
display. If you follow the suggested overpulls which are calculated for each
note, you will get close results.

Unless you are working from a stored tuning, starting from A0 is NOT a good
way to use the Verituner. Starting with A4 is important in order to get a
tuning calculated with the correct stretch to fit the piano. As for
guaranteeing 440, this is a separate issue and is not a problem - A4 is
always 440 (or whatever standard pitch you select).

I have not published at this time any comparison charts or tests showing the
results of Verituner tunings in a quantitative way. Hopefully something
along these lines will be published on our website in the coming months.
