But isn't it the case that too little Duracool will get too cold and freeze up the evaporator?

After I fixed the leak in my 4 runner I charged it with Duracool and while removing the gages I had a problem with a schrader valve causing me to loose some of the charge. I now had 20 lbs suction pressure and a not so cold suction line I also had no more Duracool so I just completed the charge with 134 out of my 30 lb jug to bring the suction to 25-30 lbs and a cold suction. I don't expect any problems and it's been awhile. I know some of you will say 20 lbs is where it should be but not in this case if the suction pressure at 20 lbs is not cold and sweaty you are under charged.
