I think the times go up and down. The lead time probably indicates # weeks until Axiom's best guess of when they're going to have to make more of that particular model. I imagine if they get more orders than expected they have to build sooner which reduces the lead time.
I haven't seen any indication that the wait times are "much less than stated", just that they're "rarely more than stated and usually a bit less". If you wait a couple of weeks the lead times will probably go down again by a couple of weeks
Seriously, you might want to give them a call and see what the situation is "right now". I expect they have to raise the lead times before they actually run out of FO stock to prevent the case where :
- they have 4 sets left
- 7 people order at roughly the same time, before the site can be updated
- 4 are happy, 3 have to wait longer than the site said
