- There are five seasons with higher R/G value than the average
 value of ten seasons. Season 2020 has been a season with second
 highest R/G value.
- The higher five seasons are the five recent seasons (2016-2020).
- The R/G value has gradually increased for three seasons after its
 minimum in 2014.
