Classic "dart burn" Steve. To me, those look like Voberry darts, the kind with the shiny vinyl tips, not rubbery like Elites. Due to the increased hardness of the vinyl, the flywheels are actually melting/grinding the edges of the tip where they first come into contact with the dart. It's to be expected with Voberries especially with better batteries. What you're seeing is a combination of missing material, and melted material mixed with blue foam dust.

Because Elites are rubbery, they withstand the initial contact with the flywheels much better. The material is able to flex and stretch rather than being grinded away. It's the same reason you can touch your finger to a bench grinder without any damage to your fingertip, but stick something hard on there and it will grind the surface right off.
