Is this a dumb question:
(Asking for a friend lol)
1. You should know the weight of the new machine when fully charged from the specs.

If you suspect a leak can you weigh it and attribute the difference to the weight of the freon?

If it's the same weight then likely that's not the problem

With only a pound or two of refrigerant in the machine, it might be hard
to tell if you loose a few ounces or not.

If you had accurate scales and knew the weight of the machine and how
much dirt and dust that accomilated on it, the method would work, but
not really practical as it only takes a few ounces difference in weight
to make a big difference in cooling.

About like having a truck with a load of bricks and weighing it and then
doing it again after one brick falls off to see how many bricks you have
on the truck.
