For it not suiting him, I was referring to its strength, as many Casters who weren't actually magicians such as Shakespear usually don't have strong NP's. Also, EX means 'It represents something that falls outside of the numerical ranking scale, a value that cannot be quantified under the normal system because it is in a league of its own, powerful to the extent of rendering comparisons meaningless.' It can't be classified because it's too strong. That NP can definitely be classified from what I can tell. I'd mark it as either C or D.
As for metal, I am incorrect. Metal is just an anomaly when it comes to the Fate universe, so you are indeed correct. My bad!
Other than that, the inconsistencies were mostly referring to what I mentioned as those were pretty drastic and seemed like stuff a beginner would do to make their characters seem stronger. So yeah, overall besides the NP you're all good!
Thanks for the input, I will change it to C rank.

Based on your description of his NP, would it be correct to say that it is similar to Telekinesis?
While the NP can be used to make a passable impression of telekinesis, it would certainly require a whole lot of effort to replicate the effect. Newton can't directly control the movement and trajectory of things like one with telekinesis would, but rapidly changing the center of gravity' attraction in different directions could certainly make it look like that (this of course require great computational skills but given who he is and his Skill that lets him see the numbers for anything and everything, it's perfectly doable).
As an example, if you have an apple in hand, a telekinetic can seize the apple and move it to his own; Newton can't seize the apple, but he will change the apple's gravity center to his palm, and following the laws of gravity, it will 'fall' in the direction of his palm until it gets there. In both cases, it would be along a single linear trajectory from one hand to the other.
Note however that the same telekinetic could seize the apple and move it to his hand in a parabolic trajectory, over, say, a wall, with no additional effort on his part. Newton can't do that directly, because objects fall in straight lines when not given additional momentum; the apple will 'fall' towards his palm and get stuck against the wall, the same way we stop falling towards the ground if a platform obstructs our fall.
Strictly speaking he
could replicate the effect by changing the apple's center of gravity to some point above, causing it to 'fall' upwards for a bit, then start moving the new center of gravity such that the apple constantly keeps changing the direction it's 'falling' in, and to a casual observer it does look like the apple is moving in a parabolic trajectory over the wall. The man does have the knowledge of physics (duh!) to calculate where to place the new center of gravity for such things, but it's largely unnecessary/tedious/annoying/prana-intensive since it requires applying his NP over and over again.
I'm not certain as to what the best way to describe it in terms of comparisons is, largely because nothing quite like it comes to mind...
