This is a big key, are you using an analog or digital hygro? Spend the extra money on the digital if you have an analog. Also, I have never had luck with the "salt test." Get yourself a Boveda calibration kit. I know tampahumidor.com will send you one when you purchase a digital hygro.
How the cigars taste and feel really is the ultimate test. I had the same issue as you a long time ago. Turned out the hygro was bad. My cigars were soo soggy from the extra humidification. I was more concerned with the # vs the cigars.
