I finally hacked my GH2- did I?

HACK INTERFACE: LOOKS MORE COMPLICATED THAN IT IS
I don't know why, but there was a huge mental barrier to hack my GH2... which I overcame today. There were a few reasons: I wondered whether or not I needed the hack, if I was jeopardizing the stability of my camera and last but not least: I really didn't feel like having to figure out how to do it...
The question whether or not "I really needed" the hack can be answered by a simple "no". Who needs the hack, really? On the other hand, who really needs a new camera? As far as the stability of my camera is concerned, you can always revert to the original firmware. And as far as my resentment for figuring out how to do the hack: it was quite simple. (even though I felt very insecure while doing it)
So now I am presumably shooting 24P with this patch: Driftwood_176M_GOP1_NOAQ_(QuantMeBaby v3) Presumably, because I have no idea whether or not anything has changed in-camera?! The firmware version stays the same and the little footage I've shot looks great. But so did the footage before... I cannot honestly say I see any difference... And I just noticed I used a Sandisk Ultra II, 15mb/s Class 2 card. I thought these are way too slow for these outrageous hack-datarate-numbers..? I guess this story isn't over yet...

GH2 hack: testing in the dark

The new Driftwood patch/hack for the Panasonic GH2 achieves an astonishing bitrate of 176 MB. But to be honest, the technical particularities of this accomplishment elude me; you could have told me 2000 MB and what does it say..? Numbers mean nothing.
The only thing I'm interested in is seeing it in applied in the real world. How does this hack translate into picture quality? Better dynamic range? Less noise? More sharpness? I'm looking for a video that does a side by side comparison of the original bitrate and the hacked one. But I mostly get video that is is sterile testing: a rating of noise produced by the camera when shooting at different ISO's with the lenscap on... That's not a real life test?!
Shoot the same scene with this ridiculously high bitrate and shoot the same scene with 'native' settings. That way I can judge whether I really 'need' this patch as long as I'm only publishing my stuff on the internet... and whether or not it's time to 'upgrade'. Can't find such a test. I guess one of these days I'm gonna have to try it myself. Meanwhile, here's the 'test in the dark' and a 250 MB bitrate test.
