Just brainstorming here...
- Price (simple range, like low, medium, and high)
- Weight
- Glass clarity/brightness (this is somewhat subjective, but it's also important)
- Number of mils/moa of adjustment in one revolution
- Availability of mounts and accessories??
- Where scope is made
- Customer service/support (a simple good or bad rating maybe?)
- Reticle subtensions? (reticles themselves are too subjective, but most people agree that .2 mil hashmarks are "better" than .5 mil hashmarks)
- Trying to come up with more.....
Does anyone think tube diameter being larger is a "better" thing? If so, that could be added to the list. Larger is better...
How about internals? Scope X has aluminum internals while Scope Z has steel... ??
I am not sure facts should be submitted per user. For example, if I want to review S&B PMII 5-25x56 I should find it in a drop down and that should have the facts (weight, length, does/doesn't have zero stop, elevation/windage range etc). If it doesn't exist then you can click an option to create a entry for it and it can be reviewed before being added to the list of scopes to review.
Also, there needs to be a discussion about how scopes will be grouped. If you include the reticle in the name then you can be missing out on the big picture. Lets say you look up S&B PMII GR2ID and there are 10 reviews. But unbeknownst to you there is 80 reviews for S&B PMII H2CMR and all that info is relevant except for the reticle section. S&B is also a good example of what happens when you have different options for turrets MTC/DT etc, the glass and parallax and magnification, eyebox etc is all the same except for the section on turrets. AKA instead of having the review of the parallax be spread out across 6 different scopes (S&B PMII 5-25x56 H2CMR MTC, S&B PMII 5-25x56 GR2ID MTC DT, S&B PMII 5-25x56 P4LF MTC DT, S&B PMII 5-25x56 H2CMR, S&B PMII 5-25x56 Tremor3, S&B PMII 5-25x56 LRR-MIL) they could all be grouped under one S&B PMII 5-25x56 so that you don't have to manually look at all of the different models that use the same glass, parallax, magnification adj etc just to get a larger picture. (I am not 100% sure on what is exactly the same between different models of S&B but you get the idea that depending on how this is implemented you can be missing data that is specific to the scope you want but you just happened to chose to look at a less popular reticle/turret config etc)
It would be nice to have overall score to be similar to typical reviews, have the overall score but let me mouse over it and it will show banded graph of how many people gave it 80-100, 60-80, 40-60, 20-40, 0-20 so I can see if 90% of the reviews are in 60-80 and 10% are in 0-20, it helps give perspective on if people are trying to tank reviews or a rate of lemons of that particular scope. Same thing for the sub categories as far as a banded bar graph breakdown of # of people that gave (example) Turret feel a 8 and how many gave it 0. Or not, more options isn't always better
Format:
Overall Score (Add up Major Categories)
Major Category (Avg of sub categories) - Sub Categories
(I am not going to pretend I know much about glass, this is just for example sake and you can add or remove sub categories or remove the whole major category altogether if you think it isn't useful)
Glass - CA, Edge Distortion, Brightness, Clarity, Resolution, (FOV, DOF {are these facts?}), Low Light usefulness?, Ability to cut through mirage? Or ability to see mirage?
Turrets - Crispness(?), Consistency (Overshoot bc of detentes being too deep), Ability to Determine which revolution user is at, Ease of lock/unlock if applicable, ease of setting zero stop, Grippiness(?, like stippling or cuts to make it slip less, IDK... again, just examples). You can have a rating for the markings (Hard to read, easy to read 1 mil marks but doesn't have .5 mil larger then the .1's or something IDK). Tracking error in %
Reticle - Ability to hold over, Ability to hold wind, Ability to range target (like if it has a section of the reticle with .1 mil hashes or something), Ease of use at high magnification, Ease of use at low magnification, how distracting it is(?), center aim point (like if you highly rate small center dots or prefer open center, this is very subjective and might fall under the ease of use at high/low mag), thickness (also might fall under ease of use at high/low mag).
Parallax - how forgiving it is, or how easy it is to reach proper parallax
Reticle Illumination - Might be more appropriate under facts section? Auto shutoff goodness (6 min is too short, 2 hours is too long etc)?, Extra points for off ticks between levels? # of levels? again, 6 min auto shutoff, no off inbetween are facts but also how much you value these is subjective sooo IDK.
Diopter - Also a combo of facts and subjectiveness, locking diopter is a fact but you can rate how well it locks up (Ex, constantly loses up). IDK much about diopter but I assume there is a +- range and some scopes might have a wider range then others? If true the range would be a fact but your desire to have a extra wide range may not mean anything to you.
Accessories - Sun Shade, ARD, Caps, cleaning kit, tools?
Magnification - Ring Stiffness (Or ease of adjustment?), Maybe how accurate it is to the markings?, Speaking of S&B: Tunneling (Or does this belong with glass), POI change when adjusting? Is no longer parallax free when adjusting by x amount?
Ruggedness - Not sure of a good way to test this aside from like the crazy scope checker thing the BR guys do where they put a frozen scope and a test scope on the dual rail thing and shoot it under recoil and see if the reticle moves compared to the frozen one. Or maybe how well it works under cold conditions? (Mag ring broke at 0 C or something like that). Maybe a checkbox for ever needing to be sent in for warranty work?
Warranty? I am not sure if any companies have a reputation for giving better service for a specific model or what, which means this may not be worth mentioning.
--------------------------------------------------
The biggest problem with a lot of what I mentioned above is that it is difficult to quantify a lot of them. What number between 1-10 do you give to "My TT parallax binds when rings are above 15 inch lbs", or "Mag ring broke when cold", or "Easy to cross-thread zero screws", or "Reticle was crooked" etc.
