Message worn. The thing is when the bearing failed and there was damage it won't be worn cintrifical. It will be in a oblong shape. Thats because the main brunt of force is on the crank during the up and down which the contact surface during those motions does not change.
You could also check by getting a micrometer and setting it to the conrod journal and rotating it around, If the measurement changes in certain area's the crank will have to be reground. Or if its to small at its smallest point it will be junk. This is all from a SR crank i took to the shop.
