This is what I did in my previous CC during the Olympics earlier this year, the owner offered a putter of choice to the player who did the most ranked rounds during the 17 days of the Olympics, and in that club at the tine was Sebicu, who does at least 10 - 15 Ready Go's per day, everyday, but fortunately he was Legend or Tour Legend , can't remember, but any way he was not eligible, so until I realised this I kept pace with him by playing not in RG's but an easy front 9 set up at STA.
XP's wasn't the target, but just number of ranked rounds.
It was the hardest thing to do, as two other guys were also trying very very hard to do it.
At the end I clocked up over 300 rounds and won easily.
So it is possible, if u do 500 rounds ( 9 holers quickly 15 - 18 mins per round ) that is over 125,000 plus any awards u pick up on the way.
I used the G12 - S ball mostly as I had an average to look after, heading towards legend status. I actually managed to reduce my average by 1.06 over that period of play.
All da best

PS. don't waste ur money on speed boost or Ultra boost or any of that shite, it does virtually nothing and is expensive.
