During primary I stir between 3 and 5 times a day on average. After primary is finished I stir/swirl on many different schedules depending on exactly what I'm trying to accomplish.
Now, the "when the bubbles stop for 3 weeks it's safe to bottle" thing... Whoever told you that is someone who has fairly limited knowledge of what is going on. Seriously - Hydrometer readings are the ONLY safe way to opperate, bubbles are meaningless. (not totally meaningless obviously, but they aren't an even remotely accurate way of operating)
If you don't have hydrometer readings then you really need to go buy one and take a reading right away, then another after another month has passed. That will give you some actual data to work with.
Hydrometers cost something like 10 dollars. If you're fermenting stuff without owning one you're probably throwing away money by the bucketload and are risking serious injury (not kidding about the seriousness of bottle bombs. If you bottle something and it starts back up in the bottle, or hasn't finished yet, those glass shards can rip clean through drywall, that's how powerful an explosion we're talking about. Even if they're just corked, sometimes the glass will blow before the cork pops).
Trying to make good mead (or even safe mead) without a hydrometer is like trying to paint a masterpiece with a blindfold on. It could in theory still occur, but your chances are pretty slim!
Sorry if it seems like I'm coming down on you a bit hard here, but you've been on this site for a long time, and we talk about bottle bombs and the importance of getting a hydrometer pretty much constantly. That you aren't using one is shocking to me.
I'm not hard on you because I'm upset, I am literally just worried about your safety! (especially since the advice you're getting from elsewhere is so dangerous. Plus, a hydrometer is an important tool in making good mead, rather than shooting blind and probably making very sub-par mead!).
