It's established HUNDREDS of chapters BEFORE Marineford that Haki can be sensed in those that don't even know they have it.
You obviously have limited brain capacity, so do yourself a favour and leave the analogies to the individuals that wouldn't fail an IQ test if it was tic-tac-fucking-toe, dumbass.
There isn't a single instance of CoC being detected prior to its awakening.
Tebol couldn't sense it in young Doffy.
Kaidou couldn't sense it in Yamato prior to her awakening it.
You're chatting shit.

Observation haki was simply regular precog
And armament was only allowing one to hit logia.
We're knew the absolute bare minimum. So thats hogwash.
So essentially your point is "let me show examples of individuals with haki pretimeskip" even though the concept of advanced haki wasn't expanded upon until post timeskip. But let me also ignore the statement of advanced haki users postimeskip using advanced forms of haki to sense people with coC without having to battle.
You goofed
