VCT leagues doubt

I wasn't able to find information about what is more important: map difference or round difference to qualify to playoffs?

Can someone answer this or share me the official ruleset? As I could only find that shitty "all you need to know" and Liquidpedia pages.

i think map diff first then round diff

generally they go by map diff first then round diff

its pretty easy
1st wins
2nd map diff
3rd round diff
