I am using Unity 4.6.9f1, and I can set the bounciness of my Physics2D Material to well above 100, which did not match the Lecture. Also, at a Bounciness of 1, the ball actually very slowly bounces higher and higher; the increase is almost undetectable. Have you heard of this, before? Is there a setting or box that I may have checked to make this behaviour happen? The Mass and Gravity Scale of my Game Object are both set to 1. Confused, though my results are somewhat similar to the Lecture, they are also not the same.
