For the record I really hate the name of that form.
It quite clearly is. If I'm not mistaken, judging from some of your previous posts in some threads, you consider this a mental state more than anything - the body reacting on its own to threats without the need for conscious thought. But it's much more than that - it's the only way of overcoming the current wall of progress established in the narrative by Whis all the way back in RoF.
The issue here is that the speed of brain impulses making the body move only begins being an issue at a certain threshold of prowess, because that speed is pretty much the speed of light. How much time does light need to travel say, one meter (the approximate distance from the brain to the fist?). 3.335640952 x 10^-9 seconds, to be exact. That pretty much means you can't make your body initiate moves faster than that (though it doesn't necessarily affect the speed of those moves, so superluminal is still most likely possible). In other words, as long as you think about every move consciously, you won't be able to say, throw two consecutive punches in a shorter timeframe than 3.335640952 x 10^-9 seconds. That's where the Ultra Instinct comes in - by eliminating the need for thinking, the speed of your reactions is no longer restricted by the speed of the electrons travelling throughout your nervous system - in other words your body is not held back by your brain. That way you're not only faster than before, but also able to evade any incoming attack or projectile relying only on instinct - eliminating any need for conscious thought. But whether you do or do not possess Ultra Instinct doesn't appear to be the only factor that determines your strength, since it's clearly possible to progress beyond Goku's current UI level (the Angels are faster still). Anyway, the Ultra Instinct as portrayed with Goku (a transformation) definitely does make him much faster and stronger than any of his previous forms.
