No, they shouldn’t, because scaling LS from single instances of strikes is not logical.
Did you even read or see what is happening in that feat? Wolfram’s metal is that heavy when applying force from its own weight, not from breaking concrete in a single instance.
Neither All Might nor Wolfram are destroyiny anything and then using the force they broke something with to scale from LS. Wolfram is attacking All Might and entering an actual push-struggle with several metal pillars, which, when factoring in speed, produced a certain mass, that All Might held back as it continued to push against him for several seconds.
The issue I have with Yang’s calc is that it assumes the LS from a single instance of striking, not a prolonged one. Wolfram kept pushing in order to exert that force. Roman punched once to break the pillar. If Roman had taken several moments to break through the pillar, then you could argue it would be LS based. But breaking it in a single strike is not indicative of what he can bench press at all.
Roman’s feat is more similar to Tanjiro’s than anything else. A single strike breaks object. That does not translate to lifting strength.
All Might’s feat is a push-contest. Several pillars push against him, he holds them back, their weight is calculated to find what he is holding back.
Those two calcs are not the same at all.
In order for the Yang calc to be similar, Yang would have to be pushing against the Mech for a prolonged period of time; and then you would find the force the Mech is pressing upon her NOT from it breaking concrete, but from its own weight and speed.
