Quoted from CaptainNeo:no, because it's all pound flat again. when it was new i'm sure it looked like a golf ball. But Indy500 has a ton of airballs.
If it were about "evening out" you'd have the center of the PF a mil lower than the rest. But it doesn't. Age makes impacts blend more.. and the impacts are not contrasting with an adjacent smooth surface. it does not account for the severity of the impacts in these newer games.
