If you have a bow that shoots 163 fps and a bow that shoots 167 fps and both with a 550 grain arrow, what does the difference mean at fifty yards? I have always wondered how much advantage a faster bow makes on longer range targets.

I'm not sure the difference in performance is statistically significant. Like ChuckC said, find something else to worry about, like cleaning up that release.
Fun to think about and exercise the brain but as far as practicality goes, not much application. 😀
I'm here, I'm just not getting involved in this one. Enough's been said already.
How many seconds does it take your arrow to go the 80 yards ? 80 yards = 240 feet ? 167 feet in a second. Another 70 ish feet in another second. Say two seconds to go 80 yards. At 4 feet per second faster it will be 8 feet farther in 2 seconds, assuming it keeps its speed the whole two seconds. My head hurts already. How bout them Packers ! Steve, you are the numbers guy, where are you ?
I think that's good advice Chuck. :) What got me started on this, I made a bow copied off of a 21st Century bow I used to have. I also have a 21st Century bow I bought a few years ago. The 21st Century bow is 4 fps faster than the bow I made and since I shoot during the summer with some guys at yardages up to 80 yards, I wondered if 4fps would make a difference. I would like to get any kind of advantage over these guys I could. LOL
It's a question worth pondering. BTW a clean release vs a not so clean release will change those ballistics. I myself would think about it, then worry about something else.
Could be the difference between a five or a four, a four or a three. That’s what I used to think when i shot competition years ago. Any advantage, real or conceived was tried. 4fps isn’t much but couple that with carbon super curve limbs and maybe that three is a five. Chasing scores is to me like chasing that perfect bow. That feeling of accomplishment.
Nah. Don't delete. Brain teasers are a fun way to keep our old minds working, lol!
Now, if two arrows are traveling toward each other and Train A (oops, Arrow A) leaves its station at 3:30...
To borrow from the firearms world, it would depend on the ballistic coefficient (BC) of the arrow. If it's the exact same arrow, the difference in speed will be less than 4 fps. The faster it starts, the more resistance it meets as it passes through the air so therefore the faster arrow will slow down at a faster rate.
less than a bow lengths difference at 150 yards
4 FPS at however many feet away it was originally measured so at 150 feet there won’t be much difference.
