I don’t think it makes much of a difference; if I had to say which is better, it’s obviously Zhenyuan first, followed by RT.

I think RT is better after a perfect circle. Because a perfect circle may cause cracks to form. Who can give a better explanation?

It’s better to first make it circular and then perform RT; a perfectly circular shape may lead to various defects
