It's pretty realistic. If you leave it short, it has exactly 0% chance of going in. Never miss it low, you will start making more and ending them closer. Down hill breaks more. As for short putts 3-5 ft. I don't even aim unless the break is extreme, I just hit well left or right of center, whatever the break dictates. Always give it a touch more when doing this too. 2-3 ft past is ample. Hammer em in. You ever see a pro lag a 5 footer? =) Ok maybe on extreme down hill. Just be careful! And watch the wind on those long ones, it does have a big effect.
