Mandarax sent me a couple of PMs, I think it might be helpful to share the information publicly. There's some good info here verifying how i1 Pros should be used, I apologize for the drama included.

Apparantly, Mandarax found an interesting spec on the X-rite website and interperted it to mean you needed to take readings at 0 degrees and 45 degrees with the i1 Pro. It didn't make sense to me, but hey, I'm always willing to learn. So I went ahead and called X-rite and talked to an engineer. Much better to go to the source than quibble. I mean, everyone can always learn something new. The X-rite engineer verified the 0/45 thing was part of the spec and had nothing to do with how measurements were taken. So I sent back to Mandarax:
I think you're referring to this: Measurement geometry: 45°/0° ring illumination optics, DIN 5033
That has nothing to do with the angle you take your measurements at. There is no requirement to position the sensor at 0 and 45 degrees, nor is there a method to take a measurement at 45 degrees without extensive and expensive custom fabrication of a mount. BTW, I called X-Rite, they confirmed the spec listed is a specification of the sensor, and has nothing to do with how measurements are taken. The Engineer confirmed that the technique I use for calibration is correct.
Thanks for your interest though!
Well, here's where the drama started. I'd not include it, but then I'd be censoring the conversation. Mandarax sent back:

If you knew what you were doing you wouldnt be calling anyone.
But thanks for calling and confirming that.
OK, just so everyone understands the data I posted, and as I already posted, I used HCFR and BabelColor neither of which is X-rite software. I have no idea why Mandarax persists in this belief I'm using X-rite software, but it ain't so. (If anyone else is wondering.) Also, when you think you're too smart too ask questions, you've just proved how ignorant you are. I'm an expert pilot, been there done that in the USAF and the airlines, and yet I'm always willing to learn something new. When you stop learning, you start vegetating. Anyways, I'm not proud of my reply, but I don't suffer, well you know.
Wow, get it through your head, I was not using X-Rite software! Can you not read?
And yeah, I know what I'm doing. i was curious what that spec meant. Better to ask than to be a dumb a&% and assume it was something else. Some people might be so stupid as to assume it meant you needed to take two measurements at different angles.
Don't PM me again dude. I don't like you.
(edited to remove profanity.)
Anyway, the point I'm trying to make here is that my testing methodology was correct as far as it went.
Now what does that mean? Is the science the end all? No, I don't think so. I think it can give you some objective criteria to measure. If I was a professional photographer it would be. If your monitor doesn't match your printer you can't know how photos will turn out. But that isn't what Home theater is about. It's about enjoying the movies you watch. The subjective impression is just as important as the science. That's why I caution folks that I haven't actually done a screen with the Glidden yet. I think it will be great, but I don't know yet. I have yet to have a subjective
For some, the science is all important, and there's nothing
wrong with that. Some people might prefer a slightly different picture. There's nothing
wrong with that either. The whole idea is to enjoy what you see. I measure the hell out of my system's frequency response too. And then I screw it up and boost the LFE channel. I like to feel the house shake when something goes "boom". All the effort I go too to get a perfectly flat frequency response, and then I throw it out the window. Why? Because I like it. Nothing else matters. Same with a screen. You gotta like it. Nothing else matters.
OK, I think that was important information. I'm not a fan of drama, and I won't be feeding it here. I won't be responding to Mandarax's posts or PMs, other than to say I don't respond to Mandarax.
I tried to smooth out the drama by politely and positively responding to his "play safe, spray safe" thread, but I guess that didn't help. Oh well, I tried.
