Specificity = sensitivity?
Now that you've added two decimal places to the specificity and sensitivity values, mine have gone from 99% and 98%, respectively, to both being 98.25% exactly. It seems unlikely to me that these two values would be exactly the same - is it possible that one of the values is being reported in both places?
If you're going to be just like everyone else, what's the point in existing?

Same problem here. Yesterday I had a 100/98 percent specificity/sensitivity accuracy. Now, after clicking on what appeared to be a pretty standard under the surface speck, my specificity went down from 100% to the exact 98.05 sensitivity percent, and has been following it ever since.
This may be just a temporary problem (probably a php variable mixup), but the question is: Will the specificity percent be restored to it's original value? Since I have already lost several sensitivity points due to improper calibration movies, having to accept a 2 percent drop in specificity would be really dissapointing...

I actually don't usually focus that much on my scores for the most part. I have never cared much for statistics before. However now that I have noticed them, I am just finding the changes somewhat annoying. Also, statistically curious. Ahem..... I will trade statistics for some real movies not seen by scores...

Today especially I was getting a lot of movies that were at clear focus on the surface when scrolled to the bottom of the focus range, therefore unable to get below the surface. I clicked on "Bad Focus" on these movies. Now my 100% specificity has gone to 96.32.
Should I not click on "Bad Focus" for these movies?

There is definitely something very strange about the specificity. Mine suddenly went from 100 to 94.71, although the number of incorrect answers stayed at ten, and indeed I had not made any entries, as I was unable to download any of the pictures. I wonder if they are putting data in the wrong fields -- that 94.71 is really close to my sensitivity of 95.

I'm definitely having the same symptoms - my specificity went from ~100% to the same (more accurate) value of my sensitivity (~97%). This coincided with the change to more accurate percentages.
I'm sure this will be fixed soon (probably using the wrong value in the specificity computation - as has been noted) and it's nice to have the extra accuracy!

I have to correct my second post: the values do change, though they stay in lockstep. After a half-dozen calibration movies, both figures changes from 98.25% to 98.26%. I think the sensitivity is being reported in both places.

Weird stats
I noticed the same discrepancy last night just before logging out. My specificity/sensitivity went from 99/98 to 97.70/97.70. This morning, I noticed that each time a calibration movie was scored correctly, BOTH stats went up 0.01%, regardless of which parameter the movie was testing.
