How to optimize accuracy?
Sadly, I do not own a timegrapher because the footprint is big, but I try to gauge accuracy for all of my ⌚. In doing so, I see that most, if not all, generally lose time.
I prefer for my ⌚ to gain time because I do not want to run late from the accumulation of lost time. Plus, I am not dead set on synchronizing my ⌚ every day.
I am wondering if the position in which I lay my ⌚ down affects accuracy. Now, I do not wear my ⌚ around the house and will take it off when sleeping, washing hands, or cooking, particularly with raw meat. So, abbreviated wear can slow the mechanism, but the position of the ⌚ may introduce isochronism that sustains loss of time. The pendulum motion of the balance wheel remains constant but is not invulnerable to gravity, which can increase the period.
So, does the position of the ⌚ influence accuracy?
Mathematically, it should, but maybe I got the mechanics wrong.
What is your experience?
A Swiss Army Knife.
To the second accuracy is fot essential to my lifestyle. I am more than happy to reset my watches when I wear them.

Honestly, resetting is probably the most worry free method of sustaining accuracy.
The position definitely influences accuracy. Some of my NH35 movements out of the box have ranged from -15s/day on the side, to 0s/day face up, to +12s/day face down.
It evens out throughout the day because the watch changes position a lot when it's attached to your wrist constantly moving, but if you let it sit in a single position for 2 days it can gain or lose 30 seconds and require a reset. If you want to regulate a watch in all positions, you will need a timegrapher.

Yeah. . .I need to declutter and make space for one because accuracy is important for me.
Balance wheel based watches most definitely are affected by orientation. Assuming power reserve is there, accuracy of the watch is related to a tuning of each orientation matching your approximate usage orientation. A time grapher would show you a noticeable variation for each orientation on a watch that if worn all day may otherwise appear to be pretty accurate. It is possible to advance or retard the accuracy by how you orient your watch when you take it off to sleep. However, a bigger influence is power reserve, especially if you have an automatic and didn’t have an active day.

That is what I am noticing.
I am leaving my ⌚ in a vertical position when not wearing it and noticing patent loss.
I will try lying it flat.
Thanks.
Vertical axis of oscillation usually means best conditions for oscillating, i. e. highest speed. Try the different positions, though laying them flat would be my first choice.
If you haven't got a timegrapher, try the Watch Accuracy Meter app. It's pretty good, and pretty - ahem - accurate.
I just wear the watch for a day, see where it is, and then when I regulate it using a smartphone as a timegrapher, just push the seconds ahead.
My turtle was running about five seconds slow, but the phone app said it was running 7 seconds fast dial side down. So I cranked it up to 13 seconds fast, and now it's less than a second fast now. Regulation is more of art than a science for some movements.

Agreed. At the very least it will allow a comparison against other watches in a collection. I use it on my phone, it does the job.
You could try the timegrapher app for your phone. I use it for my watches and it works well. I know it's not a replacement for an actual timegrapher but it is surprisingly accurate.
If you want an accurate spring driven watch then one fitted with GS spring drive movement is the one to go for. My Omiwatari runs at +0.25-0.3s a day. I generally set it about 5s slow once a month and forget about it the rest of the time. On the odd occasion that I forget to wind it and I notice before it has fully wound down, it nevertheless maintains that accuracy. I think that is down to the way the tri-synchro regulator is constantly self checking.
