How, when and in what order are multiple user events received by the same object?

Imagine we have 3 raise user events for the same object:

1) turn_right_left
in the action_builder initiates an action right_left which turns the object left or right
changes position according to a spline

2) swell
changes scale of object according to a spline

3) brightness
changes diffuse of an object according to another spline

What are the lags associated with receiving the events?

thanks in advance
