Looking at the algorithm tag in SO, I noticed that there are 6452 questions reported:

Yet going to the tag info page, at the same time it found 6455 of them

Earlier this morning this was true for Delphi: 5799 against 5800. This is not the case at the moment.

But it is true right now for math: 2751 against 2752. Math does not yet have a tag wiki, so it does not depend on this.

There just seem to be different counting algorithms that produce different results at times.

This may happen from time to time. We have lots of caching that may kick at different spots.

At the moment the counts are in-sync for the algorithm tag, so this was due to caching.

These numbers are cached, which explain why they're different. However, I'm surprised that they're not relying on the same cache, so it's still a bug.

the pages may also be cached and regeneated when something inportant changes – Ian Ringrose Sep 2 '10 at 12:41
