One problem though , She ages , She gives birth , I think she powers up later. So anything that is robotic left can't be that much.
She doesn't age. She looks the same at the end of Z as she did when she first appeared. And giving birth has no bearing one way or the other, she was always more human than machine. The only thing the Dragon changed was to remove her bomb.
As for powering up, that's also a non-factor in this because the Androids in Trunks future could do it. They'd only fought at half power up until they killed Gohan.
Because Tenshinhan's a completely normal human, right? I suppose he just sat around for seven years, did he?
Are you implying that 7 years of training is enough for someone likely somewhere between Recoome and Ginyu in power to match the likes of Buu? By the end of the series he'd easily be the strongest human but that doesn't mean he could go toe-to-toe with the likes of even first form Freeza.
He didn't learn any new skills, and after being on 10x gravity for a while, I'm pretty sure the effects for power gaining was decreased to an extent.
1) Who says he learned nothing new? He even comments that he's going to take what he learned and apply them in his own way (advent of the Shin Kikoho I'd bet right there).
2) Sure, he's not going to gain as much strength on day 225 as he did on day 34 but that doesn't mean it's going to be completely pointless. Goku still managed to get to 8,000, after all.
Tenshinhan used the Shin Ki-Ko-Ho, which is literally 300x more powerful then himself, and doesn't matter what his power level is.
If it's
literally 300x more powerful than himself then it obviously
does matter what his power is.

But there's no "literally" about it because it's never said how much stronger than him it is or, for that matter, if it actually has anything that could be considered a 'power level'. It may simply have the same effective 'impact force' against everyone, no matter their power.
There's no guarantee he trained for seven years,
1) Tien not training is like Goku not eating.
2) He's shown to have been training.
Tenshinhan was only stronger during the early tourney battles, and the Saiyan saga of course. That's about it; Krillin surpasses him in every following saga in my opinion.
I can buy that Krillin is stronger up to some point after the Cell Games and before Buu but during the Buu saga there's no way that Krillin's still the strongest when he's been sitting around doing nothing for the last 4-5 years while Tien's been training.
