"Then she'd spent several subjective five-days in the VR learning those moves and programming her own muscle mrmory"

The important words are "in the VR". Also mrmory is how it is spelled in my book. It just tickled my gall bladder to spell it that way too.

Nimue was operating in hyper heuristic mode in VR while she acquired those skills. Hence the term "several subjective five-days." And, no, she can't use that mode in the "real world" for all the reasons adduced. Because she has the high-speed port, she can enter that mode in VR, which Merlin cannot.

Thanks for the reply RFC- and my initial question was:

Could Merlin see a bullet -missile- coming and stop (deflect) it? (not catch it)

Assume that the assassin was 50ft away and that Merlin actually saw the muzzle flash. Given an 850 fps bullet (slow black powder), that bullet is going to take 1/17 of a second or 58.8 millisec to hist Cayleb. Normal Human reaction time is 250 millisec, but Merlin's reaction time is 100 times as fast, so 2.5 milliseconds, leaving about 56 milliseconds for Merlin to get in front of the bullet. If he is 20 feet away (typical distance for a body guard in close protection) then he will have to move at 357 fps second to get in front of the bullet. This is 243 mph. If he moves that fast, there are definitely questions that are going to be asked about him. I think the answer is no, he can't deflect the bullet.

Again. Merlin cannot move that fast so sayeth Newton.

I don't think that Merlin no matter how strong or fast he is can get traction between his feet and the ground in order to move that distance that fast.

So what we should do is use Merlin's super human strength to put a stake through this one.

You said it yourself, nerves transmit messages at 100 m/s, so for a 2 meter tall human (just to give round results) it would take 2/100 or 0,02 seconds for a message to go from the feet to the brain. 300ns would make it almost a relativistic velocity. After all, lightspeed is 0.3 m/ns (or 1 ft/ns.

My bad - should have been m not n for the time to travel one way from the feet to the brain. It is called bad typing and brain not picking up what the fingers have typed because the brain said m not n

Quick point: Lots of modern handguns shoot subsonic rounds. For example the standard load of the 38 Special is around 750 fps.

The 45 ACP is about 850 to 900 fps in standard loads. Of course a +P or +P+ will push a 185 grain JHP over 1200 fps.

Hey, what's six orders of magnitude among friends?

A: a whole bloody lot, that's what it is

20 feet? I've been assuming Merlin is standing right next to Cayleb (or Sharleyan) in this kind of scenario so that all he needs to do to catch a bullet is move his arm, not his whole body.

I base this on pop culture movies where a person (usually a bad guy) walks around with an entire parade of henchmen (some of whom are presumably also bodyguards) accompanying him.

Is 56 milliseconds enough time for Merlin to just raise an arm to intercept an 850 fps bullet?
