Extra AP tokens from weekly M+ chest

[Ysho]

I've been searching and can't find a source to explain the extra tokens in the weekly cache. Is it one extra token for each M+ completed above 10? Do they provide more AP the higher the M+ you've completed?

AFAIK it was 4m (for +10) + 500K (per +X over 10) at AK26.

One token per level above 10, yes. AP per extra token is static(save AK).

I believe they give you a higher tier of base token at 15 again, and then resume adding small tokens on top. Its basically done this way because they didn't want to create a new higher base token for every single level, so instead they give you partial tokens.

There is 1 big token at 10, 15, 20 (I assume) and smaller ones for the in-between levels. Same as in every m+ dungeon itself since 7.2
