Vent output temps at max cold setting, with blower on low is 42 degrees Fahrenheit. That being said, the thermometer reads about 36 in a cup of mostly ice. My cheapy Harbor Freight temp gun reads 36 degrees at the same vent at the same time.

This is with an ambient temp of 72 and 75 inside the car next to the AC blower inlet.

You could easily top it off a bit more, sounds like you’re in the mid 40’s. When the weather gets hotter and you drive it around for a while, keep a thermometer handy and see where it’s at, the good news is you can always add more later. If you’re happy with it that’s what I’d do. Both your high & low side pressures should go up, see what that does with your temperature at the discharge vents. Good job!
