Forgive me if this is an obvious question ,but I cant see any definitive information on BA.com

I have recently attained Silver ( I live in Sweden, so 400 TPs). My membership year has now been reset and I am currently at 0 TPs. The message in 'manage your account' now says- you need 400 TPs to retain silver or 800 for gold.

My question is: If I get another 400 TPS in what would have been my original membership year which I think is likely, will I be promoted to Gold or do I need to attain 800TPs from my now zeroed out total.

Thanks
