I would compare this website more to a very rough, speculative weather forecast. It might increase your chances to find psilocybe slightly, but not really.

My understanding is that fatalities from psilocybe (at least in Europe) happen, but are a small percentage of total fatalities, with other species such as amanita being several times more dangerous.

The risk would be consuming something that is not Psilocybe semilanceata, but poisonous enough to be lethal. Statistically, that wouldn't count as a fatality from it, but from whatever mushroom was consumed instead.

Should have been more precise, I meant fatalities from Psilocybe or little brown mushrooms that look like them.

Looking at statistics for a part of Germany (2006) again, there weren't actually any fatalities but 'only' cases of poisoning.

What it has done is surprise the hell out of me that it's worth looking for mushrooms at all in the park near me, and probably tipped me over the lip between "that's something Other People do" to "hmm, maybe I'll have a poke about next time I'm down there and see what I can see."

Not all amanita are dangerous.

True, Amanita phalloides specifically is the single most deadly mushroom at least in Germany according to (slightly dated) statistics.
