Your method of assigning points on a scale from 1 to 10 works, as long as you apply it correctly (you either have unbalanced weights or you assigned a score of 4 instead of 1).
The correct way is:
i5: 10pt x 60% + 1pt x 10% + 1pt x 10%+ 1pt x 10%+ 1pt x 10%= 6.4
L920: 1pt x 60% + 10pt x 10%+ 10pt x 10%+ 10pt x 10%+ 10pt x 10%= 4.6
As you can see, i5 wins. Again, weights and scores will differ from user to user.
Since this topic is more appropriate for Math Central than WP Central, I call it quit.

Anyhow, the Lumia 920 is not terrible when it comes to daylight photography to be honest. It might not be as good as the iPhone 5 but it's still pretty good.

This is why the day light photo of Lumia 920 is not as sharp as iPhone 5, because Lumia 920 camera lens comes with F2.0 but iPhone 5 comes with F2.4
So iPhone 5 would be SLIGHTLY sharper
From this article:
Variable aperture—will it happen with mobile phones?
Aperture refers to the iris in the lens and how open (or closed) it can be when taking photos. When the iris is opened to the max, it results in a lower F-Stop, which on the Lumia 920 is a F2.0. The more open the iris, the more light it lets in, which is what we need for low-light photography. The downside is a lower F-stop results in a softer image with less sharpness.
Most “real” cameras have this number as a variable ranging from F2.0 up to F16 or something in between and it automatically increase when you zoom in on your subject. High end DSLRs often shoot at F1.4, though those lenses are very expensive.
But when it comes to mobile phones, fixed apertures are the norm despite advantages of being able to manipulate that setting e.g. landscape shots in the middle of the day, where a higher F-stop gives you a sharper image. Like anything else though there are tradeoffs when it comes to mobile and so far Nokia does not see physical variable apertures happening anytime soon due issues with sharpness and other complications.

This below shot is not related to the topic, but I just want to show the F2.0 night shot compare to F2.4 on iPhone 5

I saw many threads here said iPhone 5 daylight photo is better than Lumia 920, in fact it's sharper, but it's SLIGHTLY sharper. Let's see if iPhone 5 got 10/10 points of daylight sharpened photo, Lumia 920 will get 9/10 points. But the important that, iPhone 5 does sharper only outdoor daylight photo, other than that Lumia 920 wins.
I don't know what the basis do people here use to compare both phones' cameras. For me, I am owning both Nokia Lumia 920 and iPhone 5. So my basis of comparing this two phones is my everyday of use. I can say that by hardware design and materials, Lumia 920 is better than iPhone 5, even it's bigger, thicker, and heavier, but it's still outshine the iPhone 5. Yes, iPhone 5 is made by elegance material like soiled alluminium, but the touch sensation of Poly-carbonate featured in Lumia is so much better. This is not included camera, wireless charge, NFC, bluetooth file transfer, HD+ Pureview with super sensitive touch display. So overall hard were Lumia 920 exeptional better than the iPhone 5. However, in term of the OS and Apps support, iPhone 5 wins without a comparison.
Come back to the camera and my everyday routines. Most people here said that more than 60% of photo they took in the middle of the day, daylight condition. I don't deny that, but let's think over, are all the 60% of the day photos are taken outdoor under the sunlight in the daylight condition? No right, as I mentioned above, iPhone 5 does better sharpened photo only outdoor, all the indoor photo is produce the same rank of Lumia 920, and in some indoor condition Lumia 920 does better, i.e. in your house, kitchen, bedroom, office, coffee shop, restaurant, subway, etc. So even in day time, you are still taking few photos under the sunlight daylight outdoor stuffs. That's is why I rated my Lumia 920 outshine my iPhone 5 in term of Hardware and Materials, and iPhone 5 is the king of OS and Apps.
These are some photos taken by Lumia 920

I only checked few pages in the sticky “Pictures/videos taken with my L920” and almost all the pictures I saw were close-ups or low light. People just don’t have great daylight outdoor pictures with sharp images of objects with defined lines. Ocean waves and clouds may be pretty, but do not make good subjects for sharpness.
Your close-up pictures are excellent, other than the food which I do not feel like it :-). However, I find the pictures with the balloons terrible. Sorry if I sound too harsh, but I can’t find anything sharp and clear in this picture: the leafs, the little gazebo to the right, the balloons and cables are all bleeding color and are blurry. Only the top-centre balloon looks good. I just don’t get why you would post this picture, it does not support your position…

Someone said lets be honest most shots are during the day outside but I disagree. I work all day and 85% of my shots are indoors in low light so 920 really is the camera for me. I mostly take pictures of my family(kids) and the 920 does fantastic job in these conditions.

At you questioned that the leaves are so blur, yes they are, because the camera focused on the nearest balloon so most of the stuffs at the back were out of focus and it became blurry.
Thanks for comment ^^

Close ups will always look better than landscape shots in terms of quality...
The 808 is a premium built.. even the internals are very well protected, every chip on the main board has a heat shield on it...it never gets hot, which is also good for the battery. So.. it will be fine even if you buy one in 2-3 years time.

Which is why I got my Lumia 920 first, then got a 808 after, Symbian is a pain. But for real, this is the best Phone. Amazing call quality, amazing sounds(both speaker and headphones), and amazing build quality topped off with the game changing camera that transcends every p&s and starts rivaling dslrs. But it ain't a smartphone, Symbian is horrible for social networking and web browsing. Thankfully my wp8 does those things very well :)

It sucks for facebook, but for twitter ... Gravity works very well. On web browser, the only way to make it work nicely is to turn off flash and java ...
As a smartphone.. I prefer over my iPhone 5.. it just depends on what is important for you, and your specific usage.
Considering that the 808 is running on an ancient ARM11 cpu ... pretty impressive performance.
