This hack will add 1 query to what you already have (for the new threads and new posts since you last logged on). This can't be cached because it is per user. If you have 10 you will now have 11 when reading from the cache. Since the cache is serialized, there is no query there. So the update to the hack dropped one query. When it updates the cache, it will add 9 queries for all of the stats being updated. So you would then have 20 queries. But the 20 queries only runs at whatever interval you have set (default is 10 minutes). Once the cache is updated, you are back down to 11 queries until the next update. This way you can have numerous stats on your forumhome and not have to worry about a lot of server load at all times. With the serialzation, you can use these same stats on other ares of the board by just including the statscache in the special templates section of the file you want to use them in and you won't have you worry about any queries there (if I understand serialization, right, anyway).

Does that help to understand this a little better.
