@Metoto might be misremembering what we know of Taylor's brain. As I remember, it's currently allocated strangely so her cognitive abilities are limited and she has way too much memory.
You're going to have to blank out the entire thing. In some more good news, it looks like the stuff partitioned for storage can't be reassigned for other duties. At least, not without more knowledge on your part. So you don't have to worry about Taylor becoming some kind of bad DC-comic mad scientist any time soon.
She'll simply have full access to the thinking parts, since her memories will be going into the giant storage partition now. Maybe some time in the future you can re-partition it when you understand it better. After all, it's not like Taylor is going to need all that space, she could potentially store millions of years of memories in there. Nobody will ever need that much room.
To be precise, we possibly could try to juice up her brain with more research, but that's not a sure thing. As of right now, she just has a lot of storage coupled with faster and easier thinking.
The Thinker rating is NOT only about what information the Parahuman can gather. Uber and Victor don't gather shit, their Thinker abilities enhance skill and technique.
Nope, their skill and technique are gathered by their power. Like, they don't enhance what they have in any way. Uber's power says he can now sidejump really well, so he can, where a normal person couldn't. To put it in such a way as to classify them precisely, their powers gather information on how to fulfill a given task, they thus gather information limited to specific skills.
Granted, both of our examples don't fit into the typical Thinker mould, but it's still the best way to classify them under the PRT Threat Assessment as they're still gathering information a normal person in their position wouldn't. The only difference here is that this information is restricted to what we're describing as "skills".
Generally though, Thinker Rating IS about what information a parahuman can gather. Contessa's scary as shit because she gathers information on how to fulfill any goal (including killing me), thus deserving a Thinker 12 rating. Tattletale can gather loads of varied information, thus she is a high level Thinker. I mean, what else would the Thinker category describe?
You're either overestimating what a properly trained PRT Mook can do, or underestimating what a generalized skill thinker with enhanced cognition can do. There's a big difference between fighting a squad of mooks with containment foam throwers (That's Thinker 4 by the way, not too shabby), and being surrounded by them. In the former case, our Thinker would be using self-built explosives, jamming comms, and engaging them from far beyond the effective range of confoam tanks. In one-on-one melee, she'd still be a far sight than even the best baselines (though limited by strength and mass unless she's taking steroids).
While you are right in that a properly prepared skill thinker could take on a PRT squad,
so could any Joe Schmoe that is prepared. Like, literally anyone could read the anarchist cookbook and do any of this stuff. If her power doesn't make her more of a threat than the average person, she doesn't need to be assigned a corresponding rating by the
Parahuman Response Team. Throwing stones at people does not give you a blaster rating. Also, yeah, Uber and Victor could both conceivably do what you're describing here, but they don't. Why don't they do this? Because they'd be up to their neck in heroes the moment they did. PRT threat assessment doesn't describe what a given parahuman could possibly do so much as what they've shown themselves willing to do. Would they go and make a point out of killing PRT mooks, the PRT/Protectorate would strike back in force, which neither of them want to provoke. In the first place, both skill thinkers we're using as a comparison for Taylor's possible capabilities (after lots of time for training) are kinda pathetic compared to most parahumans. I mean, Uber's a joke for a reason and Victor's only a real parahuman threat if he's together with Othala. Both of them are heavily dependant on other parahumans (Leet and Othala, respectively) to even matter in fights.
A generalized Skill Thinker optimally behaves more like a low-level Tinker with a broad specialty, combined with behavior fitting a low-level combat thinker.
Basically, this power should be in the range of Thinker 4-6 depending on how well it's used. That's ranges from 'one full squad of trained operatives is needed' to 'a typical trained parahuman assisting a full squad of trained operatives'. Alexandria doesn't benefit much because she's a flying brick, but the power itself ranges from slightly below average to slightly above average.
Not at all. A Tinker will, by definition, make technology that is uncommomly effective in their specialty. If our hypothetic skill thinker can make simple explosives out of household chemicals, a Tinker with any kind of applicable specialty could use the same materials to make a hoverboard and just fly away. Tinkers are, after all, bullshit. Now, the difference in regards to our threat ratings is that a tinker is expected to have his tinkertech with him and use it to fight whereas a thinker is expected to use their thinker power, whether to have the right skills to take you on or to know in advance what you're gonna do. Your equipment is typically not factored in, as the threat assessment specifically describes how hard your power is to deal with, not your preparations.
In the first place, the PRT Threat Assessment is not meant to be a guideline on how many mooks to throw at a problem, it is meant as a way for the mooks to know how to deal with a problem. A Thinker Rating of 1 means that the parahuman poses a threat just above human norms. This is literally what we're describing when we talk about Taylor's current abilities. She's likely to be just a little more skilled in any given field and can think slightly faster. There, textbook Thinker 1.
Taylor doesn't actually have any parahuman powers in the first place, so she's not even technically a thinker. We can't exactly compare her to one. Sure, she's technically capable of learning skills, but a professional cook is not a cooking skill focused thinker. Anything she can learn is within normal human limits.
Taylor, as she is right now, is no greater a problem to deal with than any other teenager around. If she decides to spend her time learning how to defeat PRT squads, she can do so. The same could be said for any other teenager. She doesn't even have any actual power and doesn't deserve any ranking above 1 any more than any nut with a few molotov cocktails. Thinker 4-6 is ridiculous. Imagine Armsmaster's face as he's being told some slip of a girl with slightly faster cognitive processes and photographic memory being considered Thinker 4. It makes no sense!
TL;DR If anyone can do it without a power, it doesn't deserve a power rating.
