Engineer interview segment explaining PBCoR as the paddle-ball coefficient of restitution and why it matters to power standards.
From YouTube: Engineer Breaks Down New Paddle Power Standards - Interview with PPL and UPA-A
Chapters: 0:00 Introductions 1:07 Curtis's background 1:51 Measuring a paddle's power: What is PEF? 4:29 How is PPL's methodology different than USAP's PPCoR? 5:34 What kind of range do paddles have for PEF? 7:41 Break-in period 11:08 Why use a pickleball with holes for testing? 13:56 Qualifying balls 17:01 How does a paddle's swing weight factor into CoR? 18:39 What about leaked stories of wonky PBCoR results? 23:38 The existing PBCoR forumla allows for paddles with same inbound & outbound velocity to have big differences in PBCoR results. Why? 33:37 Why does PPA use 50 MPH inbound, versus USAP's 60 MPH? 36:22 How tight is the correlation between PEF and deflection? 39:35 Why not use edge-to-edge deflection? 46:23 PPL's new white paper 49:37 PPL's method for spin testing 50:15 What's coming next from PPL?
