Self-regulating and manual winding question

[Roll the Lex]

So I've got a 214270 and have worn it pretty much daily (except to take showers) for about the past 3 months. It seems like every month or 1.5 months I'll notice the watch is off a few minutes.

Now when I first got the watch, I wound it up 40x and just wore it. I roughly used my cell phone to set the time and for the most part it was always accurate- I'd check the time every few days- then it seemed like one day it was just off by 3-4 minutes.

So I readjusted the time figuring it was running fast, again roughly to the same time as my cell phone. I then let the watch sit overnight with the crown facing up on its side. Next morning, it was fast by 1-2 minutes. Readjusted it and did the same thing- roughly set it to my cell phone.

Then again it seemed like it was one day off by 3-4 minutes. I read if the power reserve is low, it will run fast. So I manually wound it up for the 2nd time since I've owned it.

Now I've got it set up with the US time gov website and it's running +3 sec fast after 24hrs. So that's within specs. Nothing weird there.

My questions are:

How often do you guys adjust the time on your Rolex vs. self-regulate by lying it on a particular position?

If I wear it for 23hrs a day with mainly desk diving, is that enough to keep the power reserve topped off? Or should I still regularly wind it?

Tonight I think I'll let the Exp I sleep on its side and see what happens...

Thanks for all the input
