Let's do the math.

W has a max CD of 10 seconds at Level 18. If Arcane Mastery is active your next spell is a Q, reducing W to 6 seconds. Now you cast E, reducing the CD for W to 3 seconds and for Q to 0.2 seconds. The next Q makes your W ready again, which is followed by your R. Then all over again.

There you go.
