Its not uncommon to have above 90% relative humidity readings. I find it uncomfortable once the humidity is over 70%, but I'm really not a 'good' test subject as I have lived in Florida all my life and have gotten use to high humidities. I can tell you one thing with certainity, the insects love the high readings! 60% is a threshold in the summer.
A more consistent way to maintain humidity is to use humidifying crystals or ice crystals. Crystals can come in a jar or in a round or rectangle humidifier. Humidifying crystals will regulate your humidor at 70%. When the Humidity goes above 70% the crystals will absorb the moisture in the humidor.
