God Ki sensing

[GSM123]

I want to figure out how this works exactly. Apparently you have to be at a certain level to sense God Ki:

Spoiler

Goku and Vegeta can sense God Ki in base, but I think that was a minor question. The thing is, who else can? Hit does comment on how much SSJB Goku's Ki is rising with Kaio-Ken, and apparently Cabba senses SSJB:

But Trunks can't?

Spoiler

He does say he can feel an immense pressure from SSJB Vegeta, but it didn't sound like he could tell how strong Vegeta was from it. From what I'm getting, I think mortals have to be at a certain level to have the ability sense God Ki?

Also:

Episode: 110
Time: 12:54-13:10
Context: As Goku seems to be different from before
Krillin: "Something's different from before."
Tien: "Yes. He's emitting a tremendous amount of heat, but..."
Roshi: "His energy seems frighteningly calm."
Whis: "Let us observe for now. After all, this is the first time I've ever seen Goku san like that."

Finally confirmation of the humans being God level

I think there's just no real consistency. Piccolo and the humans could sense God Ki in the ToP and Trunks couldn't sense any of the Blues until he obtained SSJ Rage.

Does Trunks ever say he can't sense anyone in the future?

He never comments on anyone's Ki between sparring with Vegeta and fighting Black and Zamasu as SSJ Rage. He manages to sense Blue Vegetto's Ki while in base, but that was after achieving SSJ Rage as I said
