At 16 days into the testing, the 2 Dampit style humidifiers are down 6% RH from their high of 50% RH in the last 9 days. The case has not been opened since inserting the second humidifier, so as not to interfere with the testing. I suspect both humidifiers are now fairly dry, and that the humidity reading is from moisture absorbed inside the body that's now being released. I'll allow the humidity to reach 40% RH before I open the case and check the humidifiers. Can't wait to play my 414CE again.
