One of the issues I have with rtings reviews are their "numbers only" approach. I can't recall rtings surfacing any issues set by their own discovery from viewing content because as long as the numbers give an output, they use it to render a rating. Actual content should alway be used to validate the numbers.
it's always a bit of a balancing act between providing quantitive or subjective content for reviews. Personally the foundation for me reviews at TFTCentral are largely based on quantitive measurements, things i can test and compare easily, measurements i can take with equipment and software that the average user does not have access to. There are always plenty of first hand experiences from users on forums you can read, and more subjective analsysis from other review sites and particularly on youtube. i think there's plenty of those kind of reviews out there and plenty of people who will share their own experience, so my focus has always been on providing the other stuff that isn't readily available. actual measurements for gamma, white point, contrast, luminance etc using spectrophotometers/colorimeters, precise measurements of PWM/backlight regulation, precise measurements for response times, blur reduction strobing, input lag etc. I am against providing a review with just numbers, as your rtings example you mention, even though that would make my life a lot easier!

i do try to provide some subjective observations for all the measurements and provide some commentary to accompany and explain what the measurements mean, and what they will mean to most users.
it's tricky to get more subjective as a lot of the time that is going to vary depending on the user, their expectations, previous screen experience, susceptability to different things, eye sight, lighting/room conditions etc. I also only have a certain amount of time to write these reviews and so there's not always time to go any more in depth sadly. I'd probably get much less new content written if i were to do that. At the end of the day, some readers might value the additional content, some might not need it. I like to think of it as a resource to get accurate quantitive measrements and analysis, to supplement what you might find online from subjective reviews, user feedback and your own personal testing and experience if you can see a screen in person.
also based on at least three retail units with varying manufacturing dates.
thats just not realistic to expect i'm afraid, and if you think about it or were in the position of someone trying to review these things you'd see why. firstly you have no idea how much space in my office is used up most of the time with displays, boxes, cabling etc as it is?

I'm sure PCM probably has the same challenge. I've got enough monitor stuff lying aorund as it is thanks!
Secondly, to try and purchase, examine and use a screen for 2 - 3 weeks typically at a time, and then return multiple screens at my own expense and hassle is not viable. It would cost me around £4000 out of my own pocket to buy 3x LG 34GK950G's for instance. That would also likely need returns to multiple different stores if you wanted an even split of samples from different stock/manufacturing lines. There's then almost certainly challenges around them accepting returns in this way, if not the first time then certainly by the second or third time you do it to an online shop, and they cotton on to what you're doing. they're not here to loan you a screen for a few weeks then take it back and give you a full refund when it's in a state not quite "as new" given it's been unboxed and used (and often dismantled). it would also add significantly to the testing and review time, as i just dont have the time or inclination to test the same screen over and over again with different samples to see if there's any variation in the numbers. those tests all take time to do, record and then write up for the review so multiplying that by 3, even if it's only for certain parts of a review, is just too much. Finally, if that were to the the normal process it would mean i could only actually review a screen when it reached the distribution channel and was available to buy and that means i would no longer be able to give keen readers a first look at a new or forthcoming screen, regularly before it's even available to buy anywhere - as with the 34GK950 models here.
