I am currently at year 6 for LTP, with 472 XP at bank. Is my following assumption correct ?

1: next year 2022 I will be at year 7, still have 472 XP ( I won’t fly any this year) at bank, I would need another 428 XP (total add up to 900)to reach LTP?

2: if FB extend status to 2023 with same policy ( like Delta does), I will reach year 8 in 2023, and I will still have 472 at bank ( assume I won’t fly any in 2022), I would need another 128 ( total add up to 600)to reach LTP.

thanks
