I'm allergic to math so I don't want to claim anything, but the same thing was discussed a while ago on PUP forums and you can read it
HERE
There result were that if not accounting for aftermath, Stringing Pummel should be slightly better than Vsmite, altough the difference wasn't particularly noticeable.
And I still don't get what you're trying to say with your "lolpupnerf".
It's a nerf to Victory Smite, not to MNK and not to PUP.
The only thing that's going to change is the current balance between Shijin Spiral and the other two WSs.
Currently Shijin Spiral was very close to Vsmite, slightly behind I'd say, not worth for Verethragna users, but worth for Spharai users since they don't get Vsmite and Final Heaven sux balls.
Still, Shijin was very close to Vsmite even for Vere users.
If they're nerfing Vsmite, it means that the small gap between Shijin and Vsmite will close, and the first will be able to get ahead of the second in every possible situation (outside of Aby), even for Verethragna users.
Which brings us to the point that after this nerf *every monk* will be expected to get and use Shijin Spiral in place of any other WS, period.
I still don't get how all of this relates to what you were attempting to say about PUP.
