Hell it only took a few episodes offscreen for him to go from Grunt level, to being one of the strongest in the universe again who could keep up with the major leagues once more. That's rapid growth surpassing even Hank. Current guys they're fighting are enough that it took even Hank's strongest attack to finally win, and even that was almost repelled for a moment. They're not weak, yet Bill managed to be on their level in a few episodes.
