Self-match ups both have a time limiter about 90-140ish seconds but also there is a daily limit. You insta match-up until 5 points and then counter starts. and after you reach 18 points like this; you are simply done for the day; because it simply throws you in match-up void and all you will find will be 25-30 mins of match-up times to no avail.

If you are like solo-solo in this game with no alts or something of that kind; here it how it follows:

1- Reach 5 points with insta-match ups of yourself.

(From here on counter will reach 1:30-1:48 at most; then you will meet yourself again; unless there is a real player on the line waiting for match up)

2-Reach 18 points; wait for the second day.

3-On second day; complete your grind with self-match ups again.

This is the vanilla way.

However,

If you have a second account; by simply taking it to lv60; you can by-pass all the previously said limitations by simply intentionally feeding your main account. I know it's no easy business managing even a single acc but having one alt to help; goes a long long way.
