I just graphed the first number.... how many tickets are open since the different periods. As you can see here [1], the tickets that are open since less than a week remain more or less constant. Those opened between a week and two months even seem to go down a little in the last weeks.

But those opened more than two months ago just increase.

I think you are finding the answer you want in the data. If I am not mistaken, by definition those tickets that are over a week old (and still open) get moved from the "week old" category (decrease) and into the "two month old" category (increase). The same being true of "two month old" -> "year" and "year" -> "older". So you really cannot say with any sort of certainty why "week", "two_month", or "year" decrease at all.

I think you really have just roughly taken a moving average of the number of tickets opened with different window sizes. What you really want to know is how many tickets that are up to X days old are newly resolved (the ticket-resolution rate). Then, I think you could make the statements you just made.

BTW, I'm not necessarily disagreeing with your insights into ticket pathology.
