Cylinder tank volume and calculating it properly

Recovery tank capacity

Is there a reason that these butane tanks only come with 25 lbs. The capacity of the recovery tank is 80% of the WC weight listed correct? So if I have a 50 lb tank and the WC is 47lb, I can recover up to 37 lb?

There’s the thread that should end this argument… Or fan the flames , depends how you interpret
