That’s the equivalent of not leaving work early and accounting for traffic. You have to be there early to deal with potential issues. They give them a 10 min grace period too lol.
A different client is used for esports matches, my brother, they cannot enter clients outside the match, the client played in sports with normal valorant is not the same
Even if they wanted to, they can't open them before the match. I know them from the site called vct.gg. Also, if the client's link was left there (I saw it in the open qualifier section), everyone would enter.
