Espi, it's pretty easy, and as usual you're overthinking it.

The key point to remember are that the deadlift is a "hard" lift, both mentally and physically, and it does not respond well to fatigue at all.

This means that unless you're one of those rare freaks that is just a good deadlifter, you'll be better off keeping your volume very low overall and limiting the number of difficult sets. If you don't, you'll compromise performance in a hurry.

Instead of doing the "trendy" stuff like wave-loading (which has no place in trying to find a true max, at least not as you listed it here), just do something very simple. Work up to maybe 85-90% of your known best, then go from there.

Keep the reps to singles. There's no reason to do anything more than that.

With what you've suggested, you're just going to wear yourself out before you can actually hit a max. That triple with 100kg is what stopped you from hitting 110.

You want to hit 110, my suggestion would be to do maybe 60/80/90 (maybe 5-6 reps, 2-3 reps, then singles from 90 on up), then rest up and go for 110. If you get that, rest up again and add 2.5-5 kg and see if you beat it.
