Series 3 vs iPhone 7 - ascended floors comparison. What is your experience?

[Defie22]

Hello friends, I need your help or opinion.

I'm taking my iPhone 7 (iOS 11) all day long in my pocket. My Apple Watch Series 3 (wOS 4.0, w/o GSM, clean install) is on my wrist. Here is result of ascended floors from last days:

14.10.2017
Apple Watch - 9
iPhone 7 - 2

13.10.2017
Apple Watch - 14
iPhone 7 - 2

12.10.2017
Apple Watch - 15
iPhone 7 - 1

... and other days are very similar.

From my observations I know that iPhone results are correct. I figured out that Apple Watch often counts escalators as ascended floors. Sometimes I use the elevator to get down and AW are often counting that as an ascended floors. And I have to say some ascended floors from Apple Watch I can not explain.

How about your results?
Do you have similar deviation or there is problem with my AW?

Thank you for any advice or feedback.

ps. Sorry for my crappy English :/

Apple authorized service center replaced my watch for a new one. They said that the watch was defective (no more explanation).

First day with new one looks promising - counting floors corresponds to reality. Wish me luck
