A leak in one place has a different effect than a leak in another, but I can't always which ones are most problematic. I have done some expensive repairs to bass clarinets, essentially replacing most or all of the pads till everyone seals. I use a pressure machine.
When I use a pressure machine to do a professional repad on a soprano clarinet I typically get a seal that lasts 45 seconds or longer (upper joint). I use plugs in the raised tone holes and thumb tube so that I can press the ring keys very lightly. Otherwise I would be pressing the keys more than I would in a playing situation.
I don't bring every clarinet to the same reading on the pressure machine. If I am doing a quick repair on a student clarinet, I know what reading will create an acceptable repair. This will usually give me 10-20 seconds on seal with the suction test (not drawing on it too deeply).
For wooden clarinets, the trick to getting a great seal is sealing the tone holes and filling any checks. I often have to work on new (unsold) clarinets. I can turn a leaky clarinet into an acceptable one but working on the tone hole alone.
