When the sun shines on any particular wall the shadow lines vary widely, my first clue that something was up. It was noticing that that got me to check the siding closer. I saw the product arrive dry. Several pallets along driveway which was covered with pieces of house wrap. House wrap would not stay on in wind and also didn't come close to reach the ground. Proceeded to get rained on endlessly for weeks. I complained many times about storing material dry. Their solution was to pile fresh boards previously under house wrap on top of the wrap to keep the house wrap from blowing off. House wrap is great at holding water in dams BTW, as piles would get lower and the blocking to keep it from blowing away got more creative, quite often I would come home to find the material being stored in mini 'swimming pools' basically. We had extensive rainy weather the entire spring. I called attention to the wet siding with the install crew many times, they ignored me. Quite often they would just leave wet pieces leaning against the house or laying out in the lawn while they waited for the next day to try and continue working. Did not measure the MC in any way though that would have been a great idea at the time, darn it. I have endless pictures documenting the entire siding removal, Hardie siding arrival, and weeks and weeks of install progress. Probably 100 or more documenting wet conditions, siding storage conditions, near and far views of siding, views showing siding breaking beads of caulk, missing caulk, unpainted ends, etcetera. Thank you for the response.
