Taking out the O - R - B - S drop targets on a Centaur in order.

Usually if you hit the center space between the drop targets it will take both the O - R or B - S targets in order and award the extra ball. That's a 2 shot process. One time . . . and only ONE time, I shot for the O - R targets, got them then the ball rolls to the right and gets me the B target . . . life is good, 3 targets down & flashing . . . then with the ball losing some speed continues on and when it hits the right side I nudge it and instead of the ball moving down it pops back to the left and takes out the S drop target. All 4 drop targets, in order and my free ball on one shot. I never hit that same shot again but knowing I did once kept me trying for it all the time. I played 100's of games on Centaur with all kinds of multiball combo shots but that one shot always comes to mind. What can I say . . . I'm easily amused .
