I would guess yours was based on 1.0 overall (within 30%), with 1.3 for those pianos which have humidity control installed, yielding an average of 1.2. If yours would now fall in the next category of within 25% variance (1.0), your workload would drop from the current 108 to 97. If in addition usage should change to, say, 1.2 (and I think that it is likely the number would drop with the additional choices available), the workload would drop to 83.    </BLOCKQUOTE> Fred I did drop the climate to 1.0, and came up with 91. (the harpsichords I kept at .8) This increased my work load to .8 with a factor of 60 and 1.2 with a factor of 40. I had already changed the usage category to the present numbers. Wim </HTML>
