These speeds are incorrect, as well as the stated KE you posted...... You can't just make up a KE value for an arrow weight and then compare it to another arrows at it's actual KE value.

This is irreverent as a 350 grain arrow at 350FPS has much more KE than 70#. This is apples to oranges and pointless. You dropped the 350 grain arrow more than 20 ft lbs so it would look good in your graph, to attempt to prove your heavy arrow theroy. Of course everyone knows a heavier arrow carries slightly more KE as well as more momentum. This thread is pointing out that enough is enough. Out of today's high performance bows you don't need a tree trunk to kill a whitetail and have your arrow buried in the dirt on the other side.

It is also a bad comparison because you didn't pick a "bow" and use the different weight arrows out of it for a true comparison of spedd and KE.

How your graph should read for speed and KE values.....

350 gn arrow
0 yards 350 fps 95.11 ft lbs
50 yards343.19 fps 91.44 ft lbs

400 gn arrow
0 yards 280 fps69.56 ft lbs
50 yards 273.70 fps66.47 ft lbs

500 gn arrow
0 yards 252 fps70.43 ft lbs
50 yards 24.45 fps67.92 ft lbs

800 gn arrow (just to be silly [8D])
0 yards 199 fps70.28 ft lbs
50 yards 196.75 fps 68.70 ft lbs

I will make another graph as if all the different weight arrows were shot out one bow, to show no bias.
