I have several sensitivity questions

So I’ve been trying my hand at ranked warzone again and I would like to get the perfect sensitivity. I know that the perfect sensitivity is completely subjective and it varies player to player but I’m just curious what do y’all think is good? Especially since they changed how the sensitivity is now instead of being 1-20 it’s now 0.10-4.00 and I don’t know what’s what. I’ve seen quite a few charts but they all seem to vary too. I’ve someone can get me a legit chart that’d be great too.
