I've done some math that I hadn't seen done on this thread, forgive me if it's been done anywhere else. I used 2 seconds per teleport for solid chain casting, and assumed a 5 point endurance recovery every 3 seconds. If those numbers are off, please let me know. Anyways, I caclulted for 3 end/3 rang enh, 2 end/ 4 rang, and 4 end/ 2 range. Accounting for endurance regen during your intial teleports, to burn through your 100 endurance, with six SOs, all base green, not ++, the math came out as follows:
2 end/4 range = 16 jumps, 32 seconds, 8960 distance, 280/sec speed
3 end/3 range = 22 Jumps, 44 seconds, 10560 distance, 240/sec speed
4 end/2 range = 27 jumps, 54 seconds, 12060 distance, 223.33/sec speed.
Now, if we assume 3/3 is the 'base', we can compare the distances and speeds of these three configurations.
2 end/4 range is 81% the distance of the 3/3 config, and so on. So, here it is.
2/4 81% distance, 116% speed
3/3 100% distance, 100% speed
4/2 109% distance, 97% speed
It seems that the 4/2 combination is the sweet spot. But, if you find yourself getting to where you need to be without needing to take a break, the 3/3 or even the 2/4 might be good for you. Later tonight I'll do the math for just 3 slots, in case you dont want to 6 slot your travel power.
