Echoed Voice, Technician, STAB, and Choice Specs?

Question

What would be the power of echoed voice if, say Smeargle, were to use it wearing Choice Specs? He has technician and STAB, so what would that factor up to on the last echoed voice?

Answer 1

Turn 1: 40 x 1.5 x 1.5 x 1.5 = 135
Turn 2: 80 x 1.5 x 1.5 = 180
Turn 3: 120 x 1.5 x 1.5 = 270
Turn 4: 160 x 1.5 x 1.5 = 360
Turn 5: 200 x 1.5 x 1.5 = 450
