The right chemical quantity for old Jobo 2563 Tank?

Hi Folks,

I am going to buy an old Jobo 2563 tank and the reason why I call it the "old 2563" is that it has different chemical quantity recommendation(from the table on the tank body) than the one sold by Catlab (the official importer of Jobo in U.S.)

Old one:

New One:


As you can see, they recommend 1000ml(old) vs 850ml(new) for developing 8 roll of 120 film.

So I want to know which table should I follow?

Thanks!

Best
Leo
