Actually- did a little digging.
In 2019, when he first played significant time, his win percentage was 54%. 2020 up to 87%, 2021 up to 92% & 2022 up to 95%.
In 2023 it dropped to 77% & increased in 2024 to 79%.
So, those 2 years aside, his win ratio increases the longer he plays.
Interestingly- the 2 years it dropped- just happen to coincide with Api Koroisau joining the Tigers.
Api's career is longer, but switching to the Tigers he started at 19%, then 27% & this year 38%.
Point being- while they are not competition winning numbers- they do show that they appear to both improve the winning chances of the teams they play for over time.
Luai is at 40% & Api at 38% this year. If those numbers are up 10-15% next season, is the investment proving worthwhile?
