I have The Supreme Kai on the side of SuperSaiyan G3, It explains Piccolo's not wanting to fight & his inner statements of the Supreme Kai being so far above him.
Anywhere from a SuperSaiyan G2 to G3 could easily 1Shot Frieza even in his 100% Final Form, so The Supreme Kai being in the range of SuperSaiyan G3 & Piccolo somewhere above SuperSaiyan G1 yet weaker than SuperSaiyan G2 works in my view. As that could also explain the look of amazement when Goku, Vegeta were taking out Yakon & Pui-Pui also why The Supreme Kai was so cautious of them.
This also doesn't contradict any statement mad by Lord Beerus in Super Anime/Manga of Base Saiyans being weaker than Frieza.
Also upholds the & does not contradict the notion of
"What about the change in Goku’s battle power after that?
Even after the battle with Freeza, formidable enemies surpassing human knowledge appeared one after the other to face Goku. Though the power-ups received after having wounds healed became small, Goku and co. began using transformations and fusions to increase their battle powers, to the point where they could no longer be measured numerically…
The ending paragraph seems to mostly be a way of explaining why no battle powers are available after the battle with Freeza, saying that past this point battle powers become simply immeasurable. The way the note about near-death power-ups becoming “small” is phrased in Japanese (sukunakunatta), it could either mean that they became small, infrequent, or simply insufficient."
in any way shape of form.
Android18 vs Base Kids.
Android18 vs Base Kids where Kids are equal to or stronger.
Nothing suggests Kids are equal to or stronger than Android18 at that point.
Nothing from the guide or the material itself.
Nowhere in that phrase of "demonstrating strength on par with No. 18's" ever suggested Android18 went all out or even took them as a serious threat.
No time was there ever any suggestion she saw them while in disguise as Saiyan or anything beyond a human.
Nor does it ever suggest she would risk the life of her daughter & go all out while she's in the stands below.
Which explains her surprise & look on her face when they tossed a high powered Ki Blast that missed, backing the reasoning of why she ended the fight, which also stacks again the claim of their supposed equal strength.
Evidence of her concern for her daughter below.
