non-supernatural mega-scientist Precognition ? ie Velma Dinkley

[Plane]

B77 defines this as a supernatural mental advantage, but I'm wondering if we added enough limitations if it might be feasible to include this as a type of non-supernatural one just available to very intelligent/observant/imaginative folk.

In this case it wouldn't be able to predict entirely surprising things (ie an alien spacecraft you weren't aware of crashes to earth at that exact moment) but instead reveals what will happen so long as you are 100% aware of all contributing factors to that thing which will happen.

I was wondering about this when I saw what Velma did in the latest Scooby-Doo film (The Sword and the Scoob)

In this case it's clearly "seems like magic" level type of predictions because Velma isn't just predicting the reactions of inanimate objects, but also that of people/animals, knowing exactly how they will flinch to trigger the next stage of events:

1) knows man will duck to avoid flag rope, causing his hat to come off
2) knows momentum of falling flag flapping will thrust hat into air
3) knows the hat will fall on the goat's head to spook it
4) knows man will chase after goat, and accidentally hit an archer
5) knows archer will release arrow at perfect angle so it will hit the suit of armor the polisher is polishing
6) knows polisher will turn and glare at archers, knocking his elbow into suit of armor
7) knows suit will fall at angle to domino entire row of suits
8) knows there will be chicken eating snacks next to last suit of armor (albeit she could engineer that by putting feed there)
9) knows spooked chicken will lay egg with such force/direction it will propel thirty feet into the air and land exactly on wood chopper's head
10) knows spooked chopper in surprise will pull axe out of trunk so forcefully he loses grip on it and throws it behind him
11) knows axe has enough force in the proper direction to chop through a pillar in the courtyard
12) knows that the falling pillar will fall exactly on the Black Knight's head

Stuff like this has happened before in the SDverse (though more often I think with Fred's traps) but this is the most dramatic one I can remember seeing.

It really does make her seem like a legit wizard (and we can't really rule that out when you see the ending) even if she doesn't acknowledge it (perhaps is unaware) but I suppose it's possible within the realms of ultraphysics to predict/engineer these kinds of circumstances...

I just wouldn't know how to stat someone capable of this in GURPS terms, wouldn't know what kind of technique(s) to roll for this kind of thing. Precognition in GURPs terms seems more reactive than proactive.

In theory since you can alter the future based on a precog decide on a course, see what happens if that course is followed, and then alter your intended course repeatedly until seeing the future that you desire... but that seems like it would be a very difficult thing to do.

B66 talks about 10 minutes concentration / 2 FP / IQ-8 for intentional uses... the amount of corrections you'd need would require reducing that to 0 FP, probably just 1 second of concentration per use (if it was a free action you could probably still only do it once per second, right?) and Reliable/Talent to offset the penalty (unless you just happen to have IQ 24 or something massive which makes the penalty moot)

That's all just to see the amended future though: what kind of skill rolls would you make for knowing what microadjustments you ought to make to move towards a desired outcome?

Powers 68 talks about how precogs should be "somewhat vague" and never gives "hard facts" except on a critical success, so it might be that something like this isn't really doable unless you're spending Bonus Character Points to upgrade to a series of critical passes?

This also definitely seems like it has the "Directed" enhancement for intentional uses (introduced on Powers 68) because otherwise just brute-forcing precog checks once-per-second would give you a bunch of random info unrelated to your desired prediction (like "directive: show what happens to the black knight")

Velma vs. BK scenario (aka "Physics!") seems like a complex working of how you might combine a pseudo-precog advantage with skills like Strategy / Tactics / Traps and others I'm not thinking of...

Maybe at high enough skill levels (it feels like you'd need to be at least 40+ to pull off something with this kind of precision using components like 2 animals and 2 humans... including stuff like Animal Handling?) certain abilities function like a limited precog? As in you can so accurately model behaviors of humans/animals that you can use them like you would a spring or cog in a machine?

To model "can they pull this off" via dice, I'm wondering if it would make sense to treat this as something akin to a "Super-Invention" like how Supers 74 lets you design "One Use Only" gadgets, or Supers 112 talks about One-Use Powers.

In this case it's not so much actually designing "a sci-fi gun that does 10d crushing" or something like that though, but the result instead is compiled from mundane things/creatures and appears to just be a collection of mundane things: it just so happens you can make it so a nearby pole falls on your enemy, but in a very delayed and distracting fashion that entrances the viewer that they just don't see it coming...
