If the freeze line is slightly sharp but the strobe line is moving left, What do I prioritize?
The freeze indicator shows the pitch shortly after the attack and the strobe the live pitch after that. If there is a difference between the two, it means that the pitch of a given notes varies during the sustain of a note. I would tune so that the freeze indicator is as close to zero as possible, as short notes are more common in actual music.
Another app I used had a lock to lock the tuning curve, do I not need to do this with this app?
Pianoscope only changes the tuning curve if you deliberately re-measure the inharmonicity or change an instrument setting like the concert pitch, tuning style or temperament. It never does this implicitly, so there is no need for a lock to prevent this.
I have a single piano, bought new about a year ago. Should I change any default settings?
Most default settings are a good start for a standard tuning. You should however consider the choice of concert pitch as it can depend on the current condition and tuning state of an instrument.
If the piano is drifting with the seasons in concert, should I change the target pitch each time and go with the flow , or should I pick a single pitch and force the retune.
Both approaches have their merits. Pianoscope Pro has a function to float the pitch. This means it calculates a concert pitch which results in the least amount of pin movements (Optimize Concert Pitch). This can save you some work when tuning. But over multiple tunings this can result in your instrument become more flat over time so that after a while a pitch-raise back to a higher concert pitch may be necessary. It also depends on whether you are playing together with other instruments which have their own concert pitch requirements.
If the former, should I set a new target pitch and zero the app, or just pick a number (eg -0.5c) to aim for. Should I use a new piano file for the season ?
You should pick a new concert pitch. The Optimize Concert Pitch function of pianoscope pro can help with this. You don't need to use a different file for different seasons, but you can if you want to.
Should I set the inharmonicity weighting to 100, given it's a single piano?
For a start, I would keep it at the default.
If a note sounds good but is a few cents off, is it best to leave it? what's the limit in c?
A single note sounding good on its own simply means that the two or three strings of its unison don't produce any audible beating. But this does not mean that intervals with other notes sound good. Pianoscope is calculating a pitch for every note so that most intervals sound as good as possible. So you should tune all notes to the pitch pianoscope is suggesting. You should aim for being as close to zero as possible, not further away than 0.1 or 0.2 cents. For high treble notes this is harder to achieve and you usually can allow a larger difference.
