Yeah and you are not just talking to someone who just started testing out betas. You are wrong, I can actually do that and look at the numbers I see in front of me and say OS has changed!

It’s a controlled environment per say, nothing’s changed, same user, same tasks with little to no variability, same device, same apps, same usage and also the same person.

The only thing that has changed is the OS. Having said that, there has only been two tests so far. What I’d like to point out is that you clearly don’t have a clue what you are talking about and this is defiantly way out of your league to even understand, so do yourself a massive favour and leave it to the pros here.
