Kefla took a clean hit in the gut from Goku and kept pushing. Goku took a clean hit from Kefla and got ONE shotted KO'd out of Blue. That demonstrates the power of Genki dama.
I actually somewhat agree with that. I mean the kick could not only demonstrate the power of the Genkidama, but it could mean Kefura was possibly suppressed and then powered up without warning. Either that, or like any Saiyan (Considering how both Kale and Caulifla got gradually grew more and more powerful) got more powerful in the middle of a battle then overpowered and knocked down Gokou.

Except in this case, the context IS Kelfa actually being equal to the Genki dama in raw power.
Well she's stated to rival the Genkidama as a Super Saiyan rather than straight up match it. Also that statement of Whis' shouldn't be seen not only as a comparison of power between Kefura and the Genkidama but also as a comparison in role/ability as well. Rival doesn't necessarily equate to match.
Whis: -「今度の発動の引き金はおそらくケフラさん」
Kondo no hatsudou no hikigane wa osoraku kefura-san
The trigger this time appears to have been Kefura
Beerus: -「奴の巨大な気が…」
Yatsu no kyoudai na ki ga...
Her gigantic Ki...
Whis: -「ええ。元気玉を浴びた時のパワーに匹敵するほどのケフラさんの気が悟空さんを刺激して、またひとつ己の限界の殻を破ったのでしょう」
Ee. Genkidama wo abita toki no pawaa ni hittekisuru hodo no kefura-san no ki ga gokuu-san wo shigekishite mata hitotsu onore no genkai no kara wo yabutta no deshou.
Indeed.
I presume Kefura's Ki, who rivaled the Genkidama, acted as a stimulus and allowed Gokou to once again break through his limits.
