Harder than curse mode for sure. The lab experiment can simply not show up, or you don't have enough triggers, or it shows up too late and you don't have enough space in your house to trigger it. The more common Pool comapred to bequest isn't even close to compensating for this.

This run was incredibly stupid, if I take 20 runs I had that got past rank 5, this one probably had the lowest chance of finishing out of all of them. I was sitting in r8c5 with 0 keys, 2 rooms later I get the 20 steps dare and I have 23 steps, and I somehow make it? Absurd.

Made some mistakes at the end, I forgot I had car keys which could've given me an upgraded boudoir, didn't deactivate the experiment so I ended up with an extra 5th dare, and didn't pick up the keys from the locker room. RNG was on my side at the very end though. Never punished. Except for all the attemps before where I got screwed in one way or another.

Some strategy in the video description.
