Status (and renewal)

Thought I could stay more in Asia this year, but turns out its not to be. I am at 228 Status points this year so far. I have a trip to from BCN to Muscat coming up before the end of the year, but not sure it will earn me enough miles (flying Qatar, Economy). And even if, I guess I be back down to Green a few days later starting Jan 2025.

Any way to calculate the miles I could earn on Qatar?! Will I actually be silver until Jan 2026, or just for the few days of Dec 2024?
Thanks
