If there is 50/50 chance to get to next room, then you have a 6.25% chance to get to the final room.

There's also the fact you're having another layer of RNG on if you actually get the portal or not. So you're technically having to roll for room one as well. Means the chances would be even lower than that.
If you added in the portal being room 1, with that math it means it'd be 72-73 attempts for the final room at around 90% chance and with the individual chance being 3.125%
Edit: This isn't even counting for gamblers fallacies with this, as well as each run being independent of one another. The math above is ONLY if it were truly 50/50 for getting the portal, then each door that you open.
The actual numbers for getting through each door we don't actually know, but they are most likely lower than the 50/50 chance being used here.
I got every "rare" item from current maps and got to 5th floor a couple of times (4 i believe)
Didn't make this thread with "omg i can't get stuff" in mind, more like I'm very surprised i get kicked out of 1st floor 4 times out of 5, when it never happened to me or my "map static" of 4 ppl before in in ShB. No salt, just surprise. Bad luck can't be happening to 4 ppl simultaneously, or we're really in it now i guess
