Mine are slower than the speeds listed, but are still more than fast enough to defeat the deer's reaction time and achieve a mortal hit, at the end of the day that's all that really matters.

The range estimation or need for it is the difference. The important thing is how long the arrow has to "fall". Obviously, the longer it takes to get to the target the more arch there is to the trajectory. The faster, the flatter, the more room for error on range estimation. Or so I think.

Good post. I would have to say that bow noise is always more important then speed. Only thing I would mention about your post is that is does not take into consideration deceleration of the arrow, especially at 30 yards. The deceleration rate for a lighter arrow I believe is higher then a heavier arrow. The figures would be off a little.

We have gotten into this before and many started actually testing the differences and many started to see the light.You have to remember that you have to figure only the miss difference in range estimation and not total drop,especially when using pins.
Try it,sight in at 40 yards with a lighter arrow at 40 yards(30 might be more realistic for most)and then walk back 5 yards and shoot it for 40 yards.Measure the miss distance and then repeat with a heavy arrow,you will be amazed at how little difference there really is in the miss difference between the 2 arrows.
Personally,I am only looking at about 1" difference with 100 grain difference according to my program,and I use it to set my pins so it is pretty accurate.
I am not saying to change poundage because that will change the difference because the energy level changes.

Let's not.
The speed of sound is roughly 770 mph which equals 1129 fps which means the sound of the bow goes 20 yds in .05 sec.
Now can a deer duck that fast...I'll leave that for another thread.

Who cares about sound? Heck I've been a diehard Oneida shooter for 20yrs. Never had a deer duck my arrow. If I'm shooting, Im sticking. The only thing you missed was air resistance and gravity acceleration at 9.8M/s/s or approx 32'/s/s. Faster the arrow the flatter trajectory.
