I mean all the numbers look good. I just switched from using paper towels in my tubs, to using Cypress and it made a gigantic difference, maybe even too much humidity. Have you tried cypress? It $2.25 for 2 cubic feet at Lowes and we've called the manufacturer and they saws used to cut the cypress are throughly cleaned before cutting cedar. Most companies just cut all woods with the same saw, no cleaning.

Granted if your humidity is constant at 50-60%, then you should be fine!
