so this bit of lore here is partially inaccurate:
The ascended form doesn't have speed penalties; the increase in muscle mass isn't significant enough. It's only the Ultimate form that comes with noticeable speed penalties.
While the Ascended form
is faster, stronger, etc. than base as you would expect of a normal, improved transformation, my read on the situation is
not that it is without speed penalties.
The Ascended form achieves its power up, as does the Ultimate form, in tandem with an increase in muscle mass. According to the wiki:
Muscle mass also considerably increases, but not enough, to weigh the user down and reduce mobility, allowing the Saiyan to retain his agility and coordination.
While this at the first read suggests that the form increases speed exactly as a standard transformation of like power, a second read shows otherwise: the text of the entry says that the form allows the (here masculine) saiyan to
retain his agility and coordination. I take this to mean that the form merely fails to slow the user down from their state prior to transformation. However, the quote above is not proof in
support of that position, but rather merely the conspicuous absence of proof
against. I take it not as the foundation of my argument, but as a supporting point to the following chain of logic.
The Ascended form increases muscle mass; this is beyond dispute. Vegeta, while using it, looks like a professional body builder. While the Ascended form is, as mentioned above, sufficiently efficient as to not actively rob the user of speed, the fact of the matter is that this would be
in spite of the additional muscle rather than because of it. The muscle inescapably presents additional mass to move and represents additional flexibility lost (professional body builders not being precisely renowned for their sit-and-reach scores). While power level clearly rises enough to counteract this deficiency, that does not mean that muscle mass simply goes away.
Consider the contrasting example of, for instance, a full-power super saiyan. A FPSSJ at 500 million is at 500 million from ki alone; their muscle definition does not change from the moment they turn super saiyan to the moment they hit 1.125 billion. An ASSJ at 500 million is at 500 million as well, but in addition to 500 million from ki is also carrying enough muscle mass to shame Arnold Schwarzenegger. Now, 500 million is 500 million, but that muscle mass still needs to be moved, and it falls on the 500 million to do it. Contrast the FPSSJ, who has all of the power and none of the muscle mass. We have, in short, a 500 kg, 500 horsepower engine, vs. a 600 kg, 500 horsepower engine. Both put out the same amount of energy, but the lighter engine is going to be better in practice regardless due to having to lug around less of its own weight, even though the heavier one definitely performs better than a 500 kg, 200 horsepower engine.
(The writer disclaims any actual knowledge that would allow them to present more accurate engine statistics, having attended a liberal arts college and majored in English. It is a vague metaphor and not intended for exact verisimilitude.)
