Sy, The first thing that came to my mind was why is someone that puts enough emphasis on teaching that she is using double S&S's only tuning twice a year? I would try selling her on the concept of so may more tunings per year that the tuning doesn't have a chance to float. Use phrases like "establishing a consistant ear in her better students for perfect tuning" and "assisting her perfect pitch students in honing the foundation of perfect A440. Otherwise, in other situations floating is almost a neccesity like tuning in a church where a piano has to match the organ. I replaced a tuner here that didn't know to ask for the temperature to be raised/ lowered to "Sunday morning" level so when I turned on the organ (we're talking real one here not electronic) to find out what frequ. mid c was at on a 4' Principal, the pipe had expanded/contracted and air density (humidity) was at a point that the piano could be matched correctly.
