A fridge tech in Phoenix showed me his gauge readings at a supply house demo and it flipped how I check sealed systems
Half the old timers at that counter still swear by pulling a vacuum and watching the needle hold for 10 minutes, but he argued you should watch how fast it climbs with the pump off and I want to know which side you all land on.

You ever watch a guy charge a system by feel instead of gauges and it just works? Had an old boy in Tucson who would put his hand on the liquid line and call it done. Drove me nuts for years. Then one summer I watched him nail a charge on a 5 ton that three of us already gave up on. The needle test tells you something but so does your palm and how the pump sounds when it loads up. The gauge climb test is just another way to feel it out.
