More important, yes. > And that too much humidity is worse than too little? Maybe yes, and maybe no. Both should be avoided. All depends on piano - old piano with marginal soundboard crown and almost-loose tuning pins, higher RH might work better for it. New piano that performs well at a lower RH, low RH may be just fine for that piano. > In other words, with an adjustable humidistat (Moisture King) and > one or two heat bars we can keep Relative Humidity at 30 % or even > 25 % and that is good, much better than swings from 25 to 85 % RH > for example ? Steady 30 or 25% is better than 25% to 85% RH swings for sure. Steady 45% or 50% is likely better than 30 or 25% RH. Steady is best. Mid-range RH is best generally. However, if the piano in question performs better at a higher or lower RH, then an RH adjusted in that direction may be beneficial.
