Kick count timing?

So I’ve read that it’s 10 movements in 2 hours and I’ve also seen 10 movements in 1 hour. The nurse at my ob’s office told me 10 in 30 minutes. Although my baby always passes it, I get stressed sometimes doing the kick counts. Today he made the count in 31 minutes but I poked my stomach to get the last two. I guess what I’m wondering is…is that a short amount of time? I’ve never seen anyone else be recommended 30 minutes. But they did tell me this when I was sick with covid so maybe they wanted me to be extra alert then and maybe now I can relax to an hour..
