Not to mention that there is no guarantee by any means that that will work. Sure you weight the outcome towards a more favorable return, but there is a lot of variance in the equation. You still have a very real chance of a) pulling a top type even if you haven't seen them all, b) pulling a low tier type even if you have seen them all, and c) pulling a weapon of the entirely wrong class, even though you don't have any points in that skill.
Much better to just take the chance immediately, as any gains will just increase your chances of living to find a better weapon later.
The only time I make an exception to this is with shortblades, if my character is reasonably comfortable with threat mitigation, as it doesn't take long to find a dagger, a shortblade, and a cutlass, leaving you with a comparatively high chance of pulling a qblade. That said, I still often end up with a decent randart shortblade or a damn lajatang.
