I brushed 130,000 on 1030, and your wear is the same. Do you think that's normal?

Masters, is this wear normal for me? Every time I grind at the 32,000 mark, the total wear is about 5-6U... I see many experts in the chat saying that using a wallet to grind at the 60,000 mark results in only 4-5U of wear... But there are also many people saying that using a wallet has a particularly high chance of getting clamped... Is there any expert who can analyze for me whether it's necessary to use a wallet to grind... Those who speak in a sarcastic manner can remain silent. I am sincerely asking here.
