Piston Carbon Patterns *pics*

Ok does anyone know whats up with these carbon patterns on the top of my pistons? I could make plenty of assumtions on my own, but i want some opinions from the people that actually might have a clue as to the issue.

I'm going to presume thats a stock untouched Superjet right there.

Perfect piston wash pattern. Nice marks around the transfer ports from fuel washing over them.

Everyone should aim for a similar pattern.
