I take some authority on this matter.
The differences between Tkomp1 and erthtk are very small, but Tkomp balances the styles a little and makes it slightly less random

#1. DM threshold is up from 120 to 130 (100 normal tk). Hits need to be harder to dm, but also neutralizes alot of the randomness. The goal in competitive play isnt to boom anyways.

#2 engage distance from 180 to 170. Slightly boosts the power of offensive openers. Also now you can force a grab on clap openers. Very slight change but varies the early game

#3. damage multiplier increased for head and crotch area. and slight tweaks to damage overall.

So basically its just a slightly refined version of erthtk. The engage distance difference will have some affect on the meta but wont shift anything dramatically.
