Gold brother.Apologies for not replying sooner although I see that Tangwena Sensei has already replied.
Once I get the smell that I really like then I will dry them really well but in reality they still won't be bone dry. It's only when I cut a small chunk off of the cob and keep it in a jar that it fully dries.
4-5g weight loss sounds reasonable, so they probably are good to be sealed up for aging at a lower temperature. You can always check them in a month or so and see if they seem more moist than you think the should be.
Try as much as possible to let your instincts guide you.
