Hi Nrotik,
While I would not go as far as Lew Rothman and say "screw the hygrometer, if it doesn't crunch or drip, it's smokeable" I would say that in most cases, 63-68 is not likely to make a lot of difference. I know there are guys who will argue that such and such, precisely, is the golden number, but unless you are stocking only one model of cigar, I doubt it will matter much on average. The reason I can say this with some degree of confidence is that if you're like most folks, you'll have everything from mild skinny sticks to fat maduros in your humi. Each one, each blend, each size will react just slightly differently to the ambient humidity (primarily in terms of moisture uptake).
I keep my box at 67-69% and in this range, most light-medium bodied smokes are perfect while some of the oilier, moister maduros (except Padrons, for some reason) will tend to be just a bit over humidified. But some time in a step-down humi does the trick for the really sweet and oily sticks. So, I tune my overall humidity for the lighter sticks and more delicate wrappers because I know the maduros and thicker wrapper sticks can take a bit more insult.
In the range you're talking about, the bottom line is this, if they're smoking fine, nuff said. If they seem to be drawing hot or the wrappers are a bit too dry for your smoking environment, then bump it up. If sticks seem to have burn problems or tend to be tight, then knock it down.
Does this help at all?
