Just to add to this 'Hardcore Mode' (I'd prefer to call it Tour mode as it would play as tough as real life tour players) discussion....
Here is the PGA Tour players' average distance and accuracy off the tee for the 2016/17 season...

and here is the averages for players with over 200 tee shots in the PS4 Society - 'TGCTours (True Sim Tour)'

Some observations...
(57 Players with over 200 tee shots)
