That certainly makes it more clear. Two things:

- It is not clear what should happen if several events of different types occur
at the same time. For instance, it would lead to division by zero in some of
the equations. It seems to me that the only valid case of having events occur
at the exact same time is to have a non-setValueAtTime event followed by a
setValueAtTime (other kinds of events should effectively degrade to
setValueAtTime, right?).

- For ramps, it is not defined what should happen if there are no previous
events (e.g. if linearRampToValueAtTime is the first event in the list).
