The trouble with DIY C02 is that you cannot regulate what goes into the tank, you are relying a system that will fluctuate with age or temperature, so the table is really only applicable when you can accurately regulate the input of C02 into the tank, otherwise the target shifts all of the time and you have no control over it.
I use a similar table, but have a system with a 2.5kg bottle, regulator and needle valve, and it works well to get the right bubble rate for my tank.
