remember that the bottom red graph applies to the Burners as well .. they have the same higher trajectory compared to other irons, including the G20's ..
Also remember the 1/2 dot forgiveness. It makes your "forgiveness circle" smaller thereby bringing you closer to the hole. So, if you can putt the lights out, your wind up with more "makeable" putts. Grab a round where you make more putts than usual and/or good vem and you're likely there. You have all the shots.
But, it ALWAYS comes down to putting.
