I've recently replaced a pump with a Grundfos Model 25S20-11 and a CSV CSV12560-3. I have an 8 gal pressure tank and have problems with pump cycling. There's a whole thread on this here:

I'd like to run the pressure switch at 45/65 but right now, even if I set the top pressure to 72, the lowest flow that has no pump cycling is 4.8 gpm. I've decided that I need a larger pressure tank and have heard that larger is better (except for the price penalty). I have limited space but can easily accommodate a Wellxtrol WX-203- 32 gal tank. One issue is whether this is large enough and I have some specific questions:
1)If I replaced the 8 gal tank with a 32, will I see about a factor of 4 decrease in the pump cycling for long running applications (irrigation) assuming all else is the same?
2) For a given pressure limit (e.g. 65PSI) I assume that the minimum flow for the pump not cycling will be the same. E.G. if 8 gpm is the lowest flow that stops the pump from cycling with the 8 gallon tank, this will be unchanged with a 32 gal tank. Is this correct?
