I evaluated at an SF10 friday for a prospective purchaser. The room had a humidifier in it so I was concerned about affects on the piano should it be moved to a drier environment. I pulled out my hygrometer and measured between 27 and 28%. Humidity here in Colorado can fluctuate from 30's in the summer to single digits in the winter. Furnace humidifier installers here recommend not turning it up past 20 in order to avoid mildew. The school district that I care for normally will see a fluctuation of pitch of up to 30 cents from summer to winter on their uprights. I never used hand lotion until I moved from Michigan 28 years ago.</span></span><o:p></o:p></p></div><div><p class=MsoNormal><o:p> </o:p></p></div><div><p class=MsoNormal><span class=apple-style-span><span style='font-size:13.5pt;font-family:"Helvetica","sans-serif";color:black'>Tom</span></span><o:p></o:p></p></div><div><p class=MsoNormal><span class=apple-style-span><span style='font-size:13.5pt;font-family:"Helvetica","sans-serif"'> </span></span><o:p></o:p></p></div><div><p class=MsoNormal><span class=apple-style-span><span style='font-family:"Helvetica","sans-serif"'>A FINE TECHNICIAN</span></span><o:p></o:p></p></div><div><div><div><div><p class=MsoNormal><span style='font-size:13.5pt;font-family:"Helvetica","sans-serif";color:black'>Thos.
