I mean not feeding onto the sprocket evenly and tending to ride the tops of the teeth. Only what happens between the chain and sprocket matters. What happens at the RD level before it feeds onto the sprocket may cause the chain to climb up, but isn't the problem itself. You can see it when the feeding section stutters as it engages instead of settling smoothly to the roots of the teeth.
