I agree that the best way is probably to charge by weight.
However, you must start with an empty system to do that. Most people here do not have the means to evacuate their systems.
Not meaning to be difficult, but in your first post you said "you really need to know actual pressures." In your next post you said to charge by weight.
They are not the same.
