New member's questions. pressure tank sizing

[anest]

A 20 gallon tank only olds 5 gallons of water, a 48 gallon tank only holds 11 gallons of water. Not going to make much difference.

I understood that will be no important difference to have the reserve of water if I change my 20 gallons tank to 48 gallons one. I'm at the point to do it, can you confirm me if I really good understood you?

A larger pressure tank is NOT going to help.
