Thanks to the AD&D Random Dungeon Generator I wrote https://github.com/bluetyson/ADnD1e-Random-Dungeon-Generator, I can parallelise, so doing this only takes less than a minute.
The basic random walk theory these talk is ‘Ahead’ is the y positive direction and always follow exits – e.g. stairs down (and can go up sometimes too).
The first 1000 dungeons I have done with 10 Periodic Checks as the DMG table calls them. e.g. a roll on the main table.
Here’s a summary :-

Here you can have the situation if you find an empy room it can have secret doors – beyond which are more rooms, which can have secret doors if empty – I have it so it follows that stack down, then goes back – e.g. Rooms are the interesting thing.
So with 10 checks, a couple of rooms is likely.
In fact, here are the medians for this batch of 1000:
monster_xp 0.0
wm_xp 0.0
monster_total 0.0
wm_total 0.0
traps 1.0
rooms 2.0
total_treasure_copper 0.0
total_treasure_silver 0.0
total_treasure_electrum 0.0
total_treasure_gold 0.0
total_treasure_platinum 0.0
total_treasure_gems 0.0
total_treasure_jewellery 0.0
total_treasure_magic 0.0
total_treasure_monster_copper 0.0
total_treasure_monster_silver 0.0
total_treasure_monster_electrum 0.0
total_treasure_monster_gold 0.0
total_treasure_monster_platinum 0.0
total_treasure_monster_gems 0.0
total_treasure_monster_jewellery 0.0
total_treasure_monster_magic 0.0
wm_total_treasure_copper 0.0
wm_total_treasure_silver 0.0
wm_total_treasure_electrum 0.0
wm_total_treasure_gold 0.0
wm_total_treasure_platinum 0.0
wm_total_treasure_gems 0.0
wm_total_treasure_jewellery 0.0
wm_total_treasure_magic 0.0
Coins 11.0
Gems 0.0
Jewellery 0.0
Magic 0.0
Total Gold Equivalent 21.5
x 13.0
y 16.0
z 1.0
Median room size is 13 by 16 – y dimensions are likely to be bigger.
So if we call a median room an exemplar, let’s have a look:
Selecting all the 13 by 16 the medians:
monster_xp 0.0
wm_xp 19.0
monster_total 0.0
wm_total 0.5
traps 0.0
rooms 3.5
total_treasure_copper 0.0
total_treasure_silver 0.0
total_treasure_electrum 0.0
total_treasure_gold 0.0
total_treasure_platinum 0.0
total_treasure_gems 0.0
total_treasure_jewellery 0.0
total_treasure_magic 0.0
total_treasure_monster_copper 0.0
total_treasure_monster_silver 0.0
total_treasure_monster_electrum 0.0
total_treasure_monster_gold 0.0
total_treasure_monster_platinum 0.0
total_treasure_monster_gems 0.0
total_treasure_monster_jewellery 0.0
total_treasure_monster_magic 0.0
wm_total_treasure_copper 0.0
wm_total_treasure_silver 0.0
wm_total_treasure_electrum 0.0
wm_total_treasure_gold 0.0
wm_total_treasure_platinum 0.0
wm_total_treasure_gems 0.0
wm_total_treasure_jewellery 0.0
wm_total_treasure_magic 0.0
Coins 60.0
Gems 0.0
Jewellery 0.0
Magic 0.0
Total Gold Equivalent 60.0
x 13.0
y 16.0
z 2.0
Periodic Checks 10.0
So these are therefore likely to have an exit to level 2 – [z = 2]
