Accuracy change/observation...

I was OCD about watch timing for the 1st 6+ months I had my BLNR. Between the Watch Tracker app and all kinds of positioning tests I got to know how my movement performed in various circumstances quite intimately. After months and months of 'testing' I refined performance into 3 categories:

• Extreme interventon relative to wear time/positioning = <+.5 SPD
• Minimal (nightly) positioning = +.5 to +1.25 SPD
• Worn 24/7 with so concern for accuracy/variance = +1.25 - +2.5 SPD

Finally, my timing OCD waned and now just wear my watch 24/7 and reset to atomic time a couple of times a month... I guess my remaining OCD is I still don't let my watch get more than +/- 15 seconds from atomic time... tending to set me watch 10-15 seconds 'slow' when I do reset it which give me a solid 1/2 month before it approaches +15 seconds vs. atomic time.

On one hand, while this OCD was a bit of a distraction, I now feel I have a more personal understanding of my specific watch because of my 'investment' in better understanding what made it tick. No regrets for me.
