sportfiend01:at this point being a legend for 6 months or so I have no idea how many rounds I have in
You have a different chance to estimate it because your score history includes rounds of about 6 months back (from 10-30 to be precise).
These are 200 AFAIR. Just subtract the CTTH and Blitz, subtract the Par3 and Par5 to get the rounds counting in this time range. Guess how many you may have played in the (short?) Legend time before that - voilà!
Your total ranked rounds are 952 now - another subtraction for the initial number!
