RE: 285 fps vs 305 fps, pin gap etc...
Mo
It is my understanding that you shoot one pin.
Let's say for comparison sake that pin is sighted in at 25 yards.
I am guessing you current set up at 285 FPS???

At 285 FPS......
At 10 yards you are 0.91 inches high
15 yards you are 1.72 inches high
20 yards you are 1.42 inches high
25 yards you are zeroed in
30 yards you are 2.56 inches low
35 yards you are 6.28 inches low
40 yards you are 11.16 inches low
45 yards you are 17.23 inches low
At 300 FPS.....
At 10 yards you are0.58 inches high
15 yards you are1.40 inches high
20 yards you are1.21 inches high
25 yards you are zeroed in
30 yards you are2.23 inches low
35 yards you are5.51 inches low
40 yards you are9.84 inches low
45 yards you are 15.24 inches low
I hope this is what you were asking for.... If not let me know.
*EDIT* I just reread you post and saw where you asked for 10 FPS. I ran a 15 FPS difference wwhen i did the calculations. Sorry about that.
To answer your questions...
If it does not affect your accuracy negatively or jeopardize your bow in any way it could only stand to help you out not only with a flatter trajectory but with an increase in KE and momentum as well.
