Imagine a WR Single for a WR Average... has that ever happened before?

If you mean getting a world record single in a world record average, it happens a lot, especially with mo3 events. If you mean 3x3 specifically, it used to happen (Shotaro Makisumi got a few), though I suspect it'll happen less and less as the single gets luckier (though Rami's 0.58 single was also part of a WR average, so not hard to imagine it happening).

Let's hope that happens in 3x3.

I honestly can't understand how it is possible to see 14 moves into the future during the inspection. A 14 move X-Cross all planned in <10 seconds...?

He probably didn't plan it as a solid 14 move sequence. To plan an Xcross, you plan a few moves for the cross and then look at cases that will be formed by those moves, and know the effect that solving those cases will have on other unsolved pieces. Rather than planning out a sequence of 14 moves, he likely planned a sequence of 3 or 4 triggers with small setups that when executed, translated to those 14 moves.

So planning during inspection could have gone something like this:
The first cross edge is in place, can place another one like this and another like this, to set up the first three cross edges. Align the cross line that. There's a pair there, but it's in a bad position. Oh look, if I move the corner over a little earlier it sets up that pair for a simple insert. Where will that leave the last cross edge? Over there. Okay, can insert that with a lefty sledgehammer.

Obviously this is ignoring the fact that Feliks checks the cross on each face, but it's possible to see how he could actually plan this in a couple of seconds, leaving time to explore a couple of promising starts.

Execution is then:
x y // inspection + first cross edge
D L // second cross edge
D (U') R // third cross edge, with a U' inserted to move the corner over to set up the pair
(U' D) // simultaneously align the cross and move the pair over
L' U' L // simple insert for first pair
U2 L F' L' // lefty sledgehammer for last cross edge
