I was just clarifying that some UW scales go to 4.3, and that is why that is their GPA. It seemed pretty obvious they had all As.
I also have a personal pet peeve of people getting too in the weeds of GPAs w/o a scale or profile. A 3.8 UW at one school to another is wildly different. I see so many people with erroneous assumptions - e.g. that UC scale is how “all HS” do it and “none” do a different GPA for a A vs A- etc. 
This isn’t you, obviously, but more than just you read these posts I assume:) I would never assume that an A- is a flat 4.0 personally.
