Killing a 25:40 mob can be killed at least 3 times in one hour if you time it enough:
Starting from 0
00:00 = 1 kill
26:10 = 2 kills
(because mobs has a little hibernation cooldown, I have to add at least 30 seconds)
50:40 = 3 kills
There lol, if it is 1 minute of hibernation i can remeasure it again
