1. While I can not verify the numbers, the numbers are consistent with how the damage values work for most other weapons; e.g. the scaling for 4* weapons stop at the end of stratum five, but enemies still gain defense per depth all through stratum six.
2. The beast bonus was simply to point out the deviation of damage against beasts as well. Really, I should have just said that they both have a "Beast High bonus" so Wild Hunting Blade doesn't actually have a bigger bonus than Hunting Blade, but I wanted to add numbers.
3. I apologize for this, I was just trying to give a visual for those people who may or may not have experience with a Cutter, though I suppose I should have just referred to the attacks as the wiki does. As for the charge hit, I didn't include it mostly because that assumes a five-hit combo which may or may not come in to play often, and the damage values for a single hit of a combo seem mostly irrelevant, simply because on average the "charge" 9th hit has around the same extra damage for Wild Hunting Blade as the "high" and "low" hits (around 20 on average). I'll add the charge damage to the OP if you'd like.
4. I'm actually not sure; I'd like confirmation on this as I don't have the means to test it properly, but throughout the years all signs have pointed to Wild Hunting Blade being slightly slower than any other Cutter line because of the phantasmal wolvers; whether it adds up is probably the key factor here, but the delayed hits seem noticeable enough.
5. I'm not so sure-- I believe Wild Hunting Blade's wolvers have extra knockback over the phantasmal swords that other Cutters have, effectively hitting enemies out of the combo; this would probably be hard to emulate but may or may not be noticeable when you're actually in combat where it counts.
6. I was actually under the assumption that Hunting Blade follows suit to Dread Venom Striker, with Wild Hunting Blade being the odd one out of the entire recipe line.

I'd love to back this up with some data but I don't have the means to do so right now; if someone else could, that would be great. I'm actually quite interested in this myself, which is why I made the thread, but I wanted to add my starting suspicions first for people to build on.

1. More specifically, the scaling after stratum five drops drastically, to the point where enemy defense goes up more than the damage dealt near the end; this is pretty consistent throughout most if not all 4* weapons.

And I'd love to test everything, but again, as of right now I don't have the means to (maybe in a few days). If someone else possibly could, that would be fantastic. >_<

Good to know that the knockback is the same, that makes things much easier. There's a few things I'd like to look in to for strong comparisons, most notably:

1. Is the delayed hit from Wild Hunting Blade slow enough to knock enemies out of the phantasmal wolver's range? Both with and without ASI increases.
2. Speaking of range, do wolver's have more or less than the phantasmal blades?
3. Is the radius of phantasmal wolver's bigger or smaller than the phantasmal blade? (basically, as an example, are the blades' radius comparable to a Brandish while the wolvers' radius is comparable to the second hit of a Flourish? Are wolver's radius more or less? etc)
4. [Harder to test]: At higher ASIs, it may be much more noticeable that Hunting Blade is faster than Wild Hunting Blade; does this speed allow HB to out-DPS WHB? (not including hitting Maskeraith's quills, just for clarification)
5. [Harder to test]: How much more/less hitstun do the phantasmal wolvers gain/lose in comparison to the phantasmal blades?

On the topic of Faust vs Gran Faust: Faust has the same charge time as a Brandish, while Gran Faust's charge time is almost twice as long as a Vortex bomb (in essence almost three times as long as most swords). Faust doing less self-curse is always a plus.
