Percent of Change
For Pro Surfers in 1980
The percent of change of the pro/champions from 1980-1990 was 22 this has increased from then to now. The number of pro/champions now is 79 so check out my math to see the percent of change.
My idea for finding the amount of champion surfers came from my love for skating and how cool surfing looks. But then to see that there that many surfers in 10 years is crazy at two time periods and the amount of change is amazing. The 259% more in 40 years, but also seems really same but that is amount of the greatest surfers in 40 years
