Hi Chris, 30% Hmmm you must have better homes than I visit. Out of 1498 measurements, I have 95 readings of less than 20%, the lowest of which was 4% and 118 readings higher than 60%, the highest of which is 84% (summer time and the living is easy?) I also have an additional 312 readings of below 30% but higher than 20%, making a subtotal of 407 pianos that are in very high risk environments from low humidity. If we add in the 118 that are too high, the total become 515, that could benefit from humidity control systems. I have not factored in the date on which the measurements were taken but if I did I'm sure it would show the low humidity during our winter.
