Yep I'm cool with tinkering. Only shitty part is I can only do this at night when I have time and when there's zero ambient light.

as in the colors were off? that happened to me the first two times I did it on my fw900. no idea why, but I've never had the problem since.NP.
Worked all night on calibrating... but after all that, it didn't save properly and the screen was messed up.

What I do now is stop the WPB procedure before it goes to 6300k, select "final setting" and okay that. No problems at all now.
The trickiest portion is determining a good G2 that won't kill all the details.
did you read the last portion of the guide? This fine tunes the LUT so you don't kill the details even while having a low G2.
I think that is a big flaw in your guide. Gamma above 2.4 will lead to a lot of detail loss in darker areas, something which can't be fixed with a LUT since many games overwrite it and prevent forced restoration. We should aim for 2.2-2.4 from the monitor itself.
there is no 6300K, the first is 9300K, then 6500K, then 5000K, then the sRGB contrast adjustment. Which one are you stopping it before? And probably not a good idea to stop it prematurely unless nothing else works.

I think you'll love the image quality once you've implemented the Argyll LUT. It's remarkable to see all that detail recovered while maintaining the incredible image depth afforded by the super deep blacks.
Another thing that I haven't yet included in the guide is the notion that deeper blacks also means that the primaries reach their full saturation potential (i.e. you end up with a larger color gamut). With even slightly raised blacks, a pure red signal (RGB [255 0 0]) will actually have a bit of residual luminance in the blue and green channels, and this will desaturate the red primary. Same for each of the other primaries. This is just one of the many reasons that having deep blacks is important.
Also am questioning how hard/easy it will be to use LUT for different apps and games.
One question: the unit I got from Vito had its G2 either on 162 or 165. Is this normal?
Which apps and games specifically?
Hard to say what normal is. I imagine it depends on the life of the tube and how the calibrator chose to set the G2. I think after adjusting my G2 it was at 138.
No specific apps or games -- just that I read some games won't let you change the LUT easily.
I heard that the older a tube gets, the lower the G2 needs to be for it to get good black levels.
yea.... especially the jpeg artifacts in dark areasIt's remarkable to see all that detail recovered
As mentioned earlier, some games will allow you to respect the pre-existing LUT, and those that won't can often be forced to respect it with tools such as cpkeeper. And for those that overwrite the LUT no matter what can still be adjusted within the game to uncrush detail (e.g. gamma sliders).
Yes I think this is true, although I think a better indication of tube life may be as described on posts 9 and 10 in this thread.
What do you mean default? Every tube is different, and even when brand new will probably have different values. The way to interpret the CB max, with respect to tube life, is to take note of how much you have to slide the value up in order to reach the luminance target.

Game's gamma slider will lower the whole gamma, not just the bottom part. Do you have any measurements with better default gamma to see how much black levels are raised?
Is there a way to see what G2 was set to from the dat file?
not sure if this is what's shown in spacediver's link, but basically use Help > Expert > Viewer and click around on the left hand side until you see a G2 parameter in the right side.
my eyes + my program tell me that 194 is about half of 254 on my screen.
194 measures 26.73
254 measures 52.4
