Pentax DSLR shutter life expectancy - Help make a database!

Ever wonder how long before your Pentax DSLR shutter will go out for good? It's one of the few mechanical moving parts left in a digital SLR, and as such, it WILL FAIL at some point. Manufacturers have an estimated shutter count for each DSLR, but those are rarely accurate. Luckily, someone has already made a website for this exact reason. It averages out the users shutter count to estimate an average for every DSLR out there. However, the accuracy of this depends on the number of users who actually take the 90 seconds to fill out their make,model and shutter count and enter it into the database. And as expected, Pentax charts are basically empty, making any estimate impossible. So, it you want to have a more accurate shutter life expectancy for your Pentax DSLR, take the time to enter your DSLR's data.

Instructions:

1. Shoot any JPEG photo with your DSLR (RAW/DNG will not work) and without editing it, upload it here (you can also take a JPEG you already shot, but make sure it was shot recently and not edited):
Check Shutter Count & Camera Manufacture Date Online - EXIF Reader
It will read the EXIF data from you photo and provide you with the shutter count.

2. Now that you know your shutter count, go here:
Camera Shutter Life Database
In the search field, enter you Pentax DSLR, and then add your current shutter count and whether your shutter is still working or not (add your name/email or use a fake one. doesn't matter).

If enough people do this, we will have a good estimate of real-world shutter life for each Pentax DSLR.

If the shutter is not working, how would one take a new photo to get the shutter count?

You can't, but a JPEG you took just prior to the shutter malfunction will be fine, if you have one. Like a week/month old will be fine. Or if you have a good estimate of the shutter count, use that. It doesn't have to be the exact number the shutter has failed, as shutter life is measured in (tens of) thousands of photos. However, the closer you are to the actual number, the more accurate the database will be, so don't enter at random.

I think it had close to 30k when i purchased it. So perhaps 45-50k now?

I don't think about it much. I'm not being paid for shoots so when it does it dies. I probably buy a k1 before it breaks anyways.

In my K5II I have 22k and counting. I'm shooting sports mostly, often it's 300-600 photos per event. Probably at the end of the year I will have around 35k. Hopefully shutter will stand before I buy K-1 (maybe in next year ?) .

I wonder whether one can get a number of data base entries big enough to draw conclusions before production of this model will have ended. I doubt it.

What can you do with this? If the distribution turns out to be very flat, it wouldn't make any sense to use the mean as an "estimate", you could use any value depending whether you are an optimist, or not.
And if the camera uses motor or part of the power train also for servicing the lens, failing of the shutter mechanism as a whole may also depend on the lenses which were used.

Don't get me wrong, I also would like to see such a data base. But just out of curiousity.
And I heard of K200Ds where the shutter failed after <8.000 actuations, as well as after >150.000 actuations. So what?

Even repair services and Ricoh will not get reliable data, as they will see only bodies where a repair would make sense (early shutter failure).
And comparing these numbers with production won't make much sense either, as older bodies with such failure will rarely see service.

Given enough data points for shutter actuation failure, you can write down a probability distribution function and estimate the probability that any given unit will fail, which will provide more information than the mean.
