Question about Everett's Quantum Theory

I ask this question only of believers in Everett's many worlds
interpretation of quantum mechanics.

How small an event will be accompanied by a splitting into (two?,
many?) worlds? Is there a world where some protozoan flicks its
flagellum and one where it doesn't? Is there a third world where the
flagellum moves only a little bit? Is there a
"splitting" (fracturing?) into infinitely many worlds, each in which
the flagellum moves a bit more or less than in the others?

How tiny (trivial) a thing is accompanied by splitting? How much
tinier an event ISN'T accompanied by splitting? If there is such a
critical size event what determines its scale? If an arbitrarily
small event is adequate why isn't there splitting into infinitely many
worlds at every instant?

How does a formalism in continuous mathematics give rise to discrete
behavior?
