Divergence can
most certainly account for General Blue gaining higher strength, as well as the Red Ribbon Army's gadgets be stronger. The change to Blue was direct; RR sent him to test out his new body, and he did very well, though he failed in the end. Therefore, more research is to be done, more advancements to be made, and a quickening of the plans as well.
The Central Games occurred on
June the 15th. The story, as it stands, is taking place on
September the 9th.
June, July, August. 3 months of research and prep-time— especially when they detected Ten with the Dragonballs. There's a reason I dropped a little hint at Ten's concern with the radar being able to detect the balls even in his
[Inventory]. It's not outside the realms of possibility that they've been watching him with a satellite feed. The only reason Goku won against them was because he straight up bumrushed them with superior power. With Ten, they've had the time to start up.
Now, as for space, well; all I'll say is that the quest to figure out what a Saiyan is, as well as the
[Techie] skill, are not just random plot points I came up with for the lulz. This is divergence, at work. If you want to talk growth speed, then Frieza reaching SS-Blue level in less than a year, all the main cast gaining incredible power in the time it took to start the Tournament of Power, and so on... If that can happen in canon, then similar things can happen here.
It's not even insane breakthroughs, at any rate. Gero was able to pump out cyborgs, androids and bio-organisms stronger than Super Saiyans. I'm sure the lowly 2nd-rate scientists at Red Ribbon can churn out something with, say.. 200-300 BP.
Have a little faith in me
