It's crazy, if you think about it, morel is 70,000, it got me thinking even more and suddenly I remember Hisoka's ranking. If by 70,000 could it be that it translates directly to Hisoka's power rating as 70? Then that could only mean Illumi is 95,000 and 100,000 is as xgenesis pointed out the Highest average power possible for a human.
And no @xGenesis, MoP is only the half of it, you have to train on your AAP, as well as PAP for more effecient KO(Uvon). It can be used well to guage combatants properly, because it's not all about dishing Hatsus then game over, i.e. Kuroro vs Silva and Zeno, there was a bit of physical confrontation in which clearly kuroro was at a disadvantage in AAP(RYU).
No matter how much Ren(MoP) you show(Gon), it's still not indicative of how good your RYU is, Gon's KO(PAP) however is highly advanced, that's why the more experienced users are always in awe.
Essentially, even if Gon is 20kMoP and Morel is 70k, Morel's mastery of Ryu or even counter KO to defend against Gon's own KO(PAP) is minute, therefore gon can dish out only 3 KO's or janken(rocks) of over almost 7k over nen reinforcment, over Morel's own defense, which probably is 5k(60%) as defense.
So that's why Gon is so dangerous, his already reached a level that can utilize 1/3 of his MoP as attack, much like Uvon can.
Of course it wouldn't kill somebody like Morel, much like Genthru survived, because Gon just physically(without nen), is far too weak agains their own Physical strength and durability.
