In the saiyan civilization, literally every single person is a warrior, and the people are grouped into classes based on their strength. It's clear that comparing Vegeta to President Obama is not a very good comparison.\Yet he gives orders to the US Army. And while they are mainly focused on fighting, it doesn't mean that everything has to do with fighting.
Err, the mere fact that it is a continuation of Bardock's special means it is completely connected to the anime, if Bardock's special is to be considered part of it. Given the amount of flashbacks that tie in with this special in the anime, I don't see it wouldn't be. It's even featured at the beginning of Kai.My point is that EoB is unrelated to the anime, not that it is more canon than it. We are talking about the manga & EoB right now, and the anime isn't necessarily connected to any of these two, which means that it can be ignored in out discussion.
Bardock wasn't at 10,000, he was only specified as being somewhere below it.How do we know this? All we know about the power of the Saiyans is that they were all weaker than King Vegeta by the time the planet was destroyed, with the highest BP that we know being Bardock's 10.000, and that Vegeta at 18.000 was far stronger than the King. How strong were the Saiyans in general? How strong were they before King Vegeta's death? The reactions of Ginyu, Jheese, and Vegeta seem to suggest that 60.000+ is so unusual, that the Saiyan is considered so impossible, that he must be a Super Saiyan or a mutant.
We know that Nappa was an elite, and he was 4,000. It's fair to say that the "standard" level is far below that.
If you'll look at the quote again, Vegeta draws a clear distinction between tranquility and purity. You don't have to be pure, you just have to have a tranquil heart. And yes, no one like Vegeta, Bardock, or Goku showed up.Well, what does having a "tranquil heart" means? Being pure? Vegeta & Bardock aren't pure. And in the course of a 1.000 years, no one like Vegeta, Bardock, or Goku appeared?
