At the end of that video they show the pins being retracted (in a little dance)... so clearly the mech has the ability to retract the pins... this is very encouraging!! If they do that, then sensors can make it possible to get spares from splits... All it would need is a sensor on the rear wall to pick up a hit on the far right or left in conjunction with a hit of the right (or left) pin to make the game retract the opposite (or adjacent) pins to simulate the action of the stuck pin flying across the lane... Maybe even an adjustable eddy-sensor (aka Roadshow etc) that can detect the proximity of the ball at the right or left... if it's close enough AND the pin on that side is hit, then the game will know that the pin should fly across... If it starts to react when the pin is struck too head on, the player can tweat it to get it right...
Also, with retractable pins, the precise timing of the struck pins can tell the game the angle that the ball went into the rack and therefore the trajectories of the struck pins can be simulated by retracting the pins that would have been hit by the flying pins!! If they work closely with Brunawick I'm sure all the information to link these timings with what pins get hit from flying pins can be worked out!! Retractable pins make all this possible!!!
Just been looking here:

Check out 'Dutch 200', 'Emergency Services', 'Grandma's Teeth'... loads of stuff for DP to get their teeth into!
It would be f-ing awesome if the various pin arrangements left after the first ball could be simulated based on the timing of the stuck pins!!! Come on DP, you can do it!!
I want to see cock and balls down there!
