Are my A/C temps normal? (vid)

2010 Prius 3 trim, 180k. I made a video documenting me using my A/C and the temperatures I achieve. My car has been sitting is slight shade all day at home. I start at 5:03 at 5:06 I roll back windows up so all are up. Feel free to skim through the video a bit. A lot of it is just showing the temperature slowly changing. After almost 20 minutes it was still 84F inside. I didn't check the A/C glass for the high or low pressure line this time, but have checked it before and don't see anything. I can't tell if it's very full or bone dry. Don't mind my hands, work is a hot and dirty place.

The video description has more to say, not sure how useful it is though. I'm really wanting to get my A/C looked at again but I don't want to spend the money and find out it's as good as it gets.

 

This is what I was thinking. I have no idea if it's been done before. I've only had the car 2-3 years. I have found that if I manually go lowest temp and 2 bars fan for a few minutes and then go full blast, it actually feels coolish right away. It feels colder than manually going low and full blast right as I start the car even after several minutes.

I checked the ac glass a couple days ago and I couldn't see anything. Not sure if it's so full or empty. I was trying to figure out the logic behind this. My guess is when it cools down enough it's some kind of efficient sweet spot that it can hold a cooler temp.
