This should come as no surprise, as Troy F already did this test. But here's the result of a 0-40y test I did with my daughter this morning at the range.

Some things from this test that stood out to me:
  • Heavier arrows lose less speed (over 40y) vs lighter arrows
  • Heavier arrows lose less KE (over 40y) vs lighter arrows
  • A moderately heavy arrow (500-600gr IMO) seems to provide the most (initial) KE
  • With a lower poundage bow, the above is exaggerated

So your sacrificing almost 6" of drop at forty to gain 5 ft lbs. 5 ft lbs 99% of the time ain't making a difference 6 inches is a big difference
The overall drop doesn't really matter, because you will be sighted in for whatever arrow weight you're shooting.

For example, my bow with 2 different arrow setups (charts from archer's advantage).

278fps arrow, total drop at 40 yards is 34.8"
338fps arrow, total drop at 40 yards is 24".

Does this mean I "miss" by 10 inches with the heavier arrow?
No. Because my 40 yard pin is sighted in with either setup.

My drop per yard with the heavy arrow is 1.8"
Misjudge yardage by 5 yards, 1.8x5 = 9 inch miss

Drop per yard with the light arrow is 1.2"
Misjudge yardage by 5 yards, 1.2x5 = 6 inch miss

Is that significant? You decide. Personally I'm going to range at 40. At 20 the difference in 5 misjudged yards between the 2 setups is 1.5".

Curious since it's not mentioned, what was the tuning done for each arrow weight?
The only tuned arrow (for the EVL) was the 582gr. That being said, all 3 flew pretty well and nothing crazy is happening on paper at least.

For the Supra, the 403gr arrow was tuned
