Ramped barrel for 45

Hi, Guys. This question is for you gunsmith types out there. Is there an advantage to using a ramped barrel for standard ball loads (not hot) for a 45 auto?

I can see a need for a high pressure cartridge like 9 Luger or 38 super but does it help a 45? If so is a Clark/Para or Wilson/Nolin better?

This will be for a USPSA Single Stack or IDPA CDP pistol needing to make a 165 power factor. (which is less than GI ball)

I personally do not think it makes a difference. From Ransom rest I've gotten same results. I've seen more issues with fully ramped barrels having feeding problems with jhp than standard barrels.
