How powerful was Gohan (Enraged against Frieza at 50%)?

I'm referring to when Gohan landed a few blows on Frieza (at 50%) in the filler arc after Goku had fallen in Super Saiyan form. After those blows, Frieza launched a Super Masenko.

Frieza then used his full power to show Gohan his true strength. Goku then returned to the battlefield and ordered Gohan to leave Namek.

What power level would you give that Enraged Gohan?

If Freeza was fighting him and still got hit, maybe 45 million. Which is extremely broken.
If if was a total surprise attack then maybe 30 million or even a bit lower could still knock him around. Still broken.

Freeza used his full power on Gohan? He went buff? Or 70%? I remember it as 70% being Freeza's full power without going buff.
