Can someone clarify

Keep reading indent vs. Faint lines.

People think they see a faint line, they're told it's an indent..

People see indents and they're told it's a vvfl.

But when you compare the two, their tests look the same..

first response is known for indents, but if you see an "indent" within the time frame it's a vvfl?!?!?

How does this even work... 😫

So wtf Is this.
