...But the odds are better, cause multiples of the same thing can drop. Like in A4 last night, two shafts dropped same run

On the other side of the coin, there is also a chance that 2 of the same thing that you don't want can drop as well, 1/3 is the same as 2/6.

One thing I wasn't taking into consideration as well is that you need multiple items to get a piece of gear. That decreases the odds of actually getting a piece of equipment as well since you have to win 2-4 times instead of a single time.
