Shots don't play the same when you move closer or further away.
For example, on BPB #15, if I'm 70 yards out, I add 11 yards to my shot (after adjusting for the wind) in order to make it to the green, which is something like 22 ft above the hitting area. When I'm 150 yards out, I add 16 yards onto the shot in order to make it up on the green.
On KIA 3, I used to drive to about 140 yards out, and hit the shot the exact same distance as the upper right hand corner said. From the championship tees, I drive to about 195 yards out, and I hit 4 yards less than what the upper right hand corner says. I have to do this because I am using a lower trajectory shot, and they will roll more once they hit the green.
Another example is BPB #8 (pretty sure it's #8, anyways -- the par 3 that is downhill like 25 ft.) If the hole location is up front, I add 10 yards to my shot. If the location is in the back, I add 16 yards to my shot. The reason for this is that I have to use a 3-iron to reach the back location, but I use a 5-iron to reach the front location, and with the lower trajectory shot for the back location, my ball will be coming in at a shallow angle, with a lot of forward progress, and that 25 ft drop in elevation will translate into 16 yards as opposed to the 10 yards that I gain with the 5-iron.
Perhaps the very best example is KIA #18. Prior to the changes, from the master tees, I drove to about 150 yards, and I would add 4-5 yards to the upper right hand corner. From the legend tees, however, I drive to about 210 yards out, and instead of adding 4-5 yards, I subtract 4 yards. The approach plays the complete opposite of how it used to.
Wind also affects different shots in different ways.
Simply put, when the tees move (as they did for you), when you get a significantly better driver, when you get new irons, etc. you have to change your shots. They won't play the same anymore.
