Maybe I worded that wrong because its late sorry
For the Tom scaling both Gap and James scale to large building one just scales to a large degree, so Tom needing to use his full power and even go beyond his limit to scale to Gap's large bulding level feat while still being weaker than James wouldn't be contradictory (we have Gap's feat at 2 tons and James's feat at 6 tons a 3x difference)
As for the holding back part that was when he fought King
My point was that the ONLY time Tom has been compared to a character that scales to large building (in this case Gap) was when he by his own admission was breaking his own body in an attempt to kill James
I said in a previous post that I am fine with the MK dads being small building+ or even bulding level but anything higher is CURRENTLY (key word CURRENTLY) pushing it
If a new chapter came out and MK used CQC and blew up a large bulding (or jist performed a feat that scales to that) then sure I would agree
As for the King vs Tom thing, Tom could have also one shotted Taejin in 1A, but he didn't, he could have one shotted both Yuseong and Mandeok in 2A but he didn't, he could have just used 3T unique skill off rip and one shot Goo before he had a chance to get his hands on a sword but he didn't, also this literally happens all the time in MK
MK, Jincheol, Hansu, Samdak, Sophia etc are all holdsback men/women, so many of their fights have them exchanging blows only for them to reveal they were holding back and then hold back less and start winning, the best argument is Tom being enraged, but he didn't use any signature moves, or animal instinct he just whailed on him, we saw in lookism when Tom is ENRAGED FR he just starts hitting you with 4T off rip, he was biting people's arms off and donuting people

King got off easy if you ask me

you can easily argue he chose to not one shot King PRECISELY because he was enraged and he didn't want King to get off that easy (actually we LITERALLY have a statment that Tom would have been disappointed or something along those lines if King couldn't at least put up a fight lol)
