This VOA was taken from 5 different brand new 1 qt bottles. I poured about 20% of the sample container capacity from each bottle. Following the VOA (for direct comparison) is the UOA I took from our '18 CR-V. I've heard that a good rule of thumb is if the UOA TAN is 3x or less that of the VOA TAN, then you didn't push the fluid too far. Going from 0.4 to 1.3 looks like I'm right in that range.
