I need to know how "it expels unrestrained wind energy" relates to "it multiplies something by 10".
Mostly because the nature of Shockwave is a multiplier. It is less that it multiplies a set value, 34.5, but more that it multiplies the value given. The 34.5 is simply what is given for the base Shockwave.
It is indeed using wind energy though, which is a stipulation.
The major problem is that it nature as a multiplier means the attack will follow how Shockwave works in nature, instead of the original,meaning an outwards burst in the general forward direction from your position using the value given of raw power in the actual attack.
Basically, you're thinking of the kills like preset abilities. Spells in a game.
But really, they're preset processes, which you use to create abilities.
Combining Shockwave with another spell, is simply taking the underlying process behind Shockwave, as in exponentially overwhelming wind energy outwards, and then applying it to another process.
It's a classic case of extreme power with little to no efficiency. As the force is wasted in every spot it hits that holds no opponent. And it obviously has no piercing power, instead applying crushing.

Can you at least understand the question now?
From those scenarios it becomes obvious that you're thinking of Shockwave as efficient.
It's not.
Shockwave is quite literally taking the SP directly, and converting it into that forward motion explosively.
It is like a shotgun(buckshot), I suppose.
The blast touching your skin is 345, then that blast spreads forward slamming into everything over the area. As you know, force spread over an area is in general less effective.
It's not converting the power into more, it is simply converting the base given into an explosion in a set direction of "forward."
Because of this factor, you are allowed to use the amount you've trained yourself capable of handling. In this case, 10x
The wind nature is what is causing the confusion I believe. Because the will of wind is to spread. So by stopping it, or focusing it all on one spot, when released, it goes everywhere in one huge "poof."
Impatience, I guess you could call it.

Have I stopped being confusing yet?
