Although I wasn't there, I am certain he has more than a "gut feeling" of assurance that more than 3-4 newtons were applied... HS level physics state that:

mass*velocity(change) = Force*time

Our minibot weighs 2.3 pounds --> ~1 kg
Our minibot travels up the pole in about 1.3 seconds --> ~2 m/s

By just saying that the minibot stops (although ours certainly is repelled backwards, too!) you get a change in velocity of ~2 m/s.

If the minibot is being slowed by the tower for less than half a second (I can't imagine one taking that long... most stop suddenly!), then the Force is greater than 4 Newtons.

(1kg*2m/s) / .5s = 4 N


I certainly hope that refs are allowed to add judgment to obvious false negatives!
