Regular tuning increases stability. Settling is a function of the magnitude of a pitch change. Whatever the pitch change, it will settle a third. A 20 cent pitch raise will settle 6 cents, a 100 cent pitch raise will settle 30 cents ; immediately . The added tension flexes the soundboard and structure. Therefore, anything more then a few cents we do twice through quickly rather then once through slowly to maximize stability. Regularly tuned pianos may only need a 3 cent or less pitch change yielding very stable tuning.
Regularly tuned pianos require less time to tuning because pitch has drifted less, Rather then a 30 min pitch raise followed by a 45 min second pass, it may need less then an hour. This leaves extra time to lubricate, tighten, voice, or regulate elements that will improve mechanics , tone and touch. We use extra time left to add more value; a reward for the easier tuning.
The piano will sounds better , and for longer if tuned regularly, so perhaps people will enjoy playing it more
It is better for the development and preservation of our ears: pitch sensitivity,. We get use to what we are exposed to.
When a piano is seen regularly we catch problems, such as structural separations, glue failure, soundboard or bridge cracks earlier when they are simpler, easier, and much cheaper to fix.
Persevere the value of your piano. It is easier to sell, thus worth more when it sound its best,
Motto ; ALL pianos may not be equal, but all pianos deserve equally to sound the best they can .
