So I was reading about competitive checks, and the example they give is confusing me .

In the example (pg 25), Oskhara generates two success and two advantage for the check. On the other hand, Lowhrick generates one success, one triumph, and three threats. Apparently, Lowhrick wins the check, but I don't understand why.

Both of them have a net success of 2, and according to the book, tie breakers are then determined by who has the most advantage, which in this case is Oskhara. So why does Oskhara lose?

Triumphs are counted before Advantages for breaking ties. This is detailed in the 4th paragraph of page 25.

Triumphs also count as successes. so Lowhrick has 2 success with a triumph.
