Black Bay 58 long-term timekeeping stability

Hi all, I'm close to buying a new BB58 that is averaging +0.5 sec/day, per the AD's testing.  This is excellent, of course. My question is whether the BB58 tends to 'settle in' or slow down over the course of the first year.  I've experienced this with various (non-Tudor) ETA movements where they start out a couple seconds fast then slow down over the first 6-12 months.  I realize this is controversial and that many believe movements don't 'settle in' over time.  Some of mine haven't, but some have.

In summary, I was curious about your longer term timekeeping experience of BB58 owners.  Have there been any changes?  Granted, the watch has only been out for a short time so 'long term' is a relative term in this case.

Thanks.

John
