Traditional packing gland procedure calls for no leak when stationary..1 or 2 drops per minute and a temp of about 30 degrees F above outside water temp when rotating.
Since the GB has the extra coolant flow from exhaust cooling water, I assume that the GB gland can be a little tighter with no leaks while rotating as long as temp is less than 30 deg F higher than outside water????????
Oxford Yacht claims to be expert on GB and they speak to having drips when rotating.
Before I bought my boat the previous owner replaced packing gland when cutlass bearing was replaced. Ran for a while with no drips ever, then the lock nuts backed off from vibration and it began leaking.
