Apple Game Frameworks and Technologies: 50 + and 60 * (?)

Please use the following format for the title of this thread (then simply delete/replace this text with the content for the thread):

Title: Apple Game Frameworks and Technologies: 50 + and 60 * (???) (page 143)

Is this intentional? lowerLimit adds 50, but upper limit multiples by 60??

let randomModifier=SKRange(lowerLimit:50+CGFloat(level),
                           upperLimit:60*CGFloat(level))
