new battle pass system

I need someone to explain to me how this new system works. before it was 1 account level = 1 battlepass level + 5 battle stars. now stars have been removed and the 1=1 doesn't apply anymore. from my understanding both battlepass and account levels use the same xp. and now reaching the requirements of a page aka "x amount of levels are needed" means when u get those requirements u unlock the whole page and you can unlock eventhing in said page. if I'm wrong please calrify. so my main issue id how much XP do I need to get 1 level in the battlepass, for example you need 80k to get 1 account level. how how many levels are needed to complete the battle pass
