This is very interesting perspective of Timo's training. 

It looks like the robot is just spitting out relatively high, but very spinny topspin to Timo at low frequencies, and he is basically counterlooping them on both BH and FH. 

I would have thought that Timo would be training with a lot higher frequencies than this (from what I saw in past with pro multiball training). Instead it looks like he is really looking to optimize shot quality, particularly the spin on his shots.
