They used 4000 on the first day. There were 360 there including competitors, marshals and partners. So that's about 10 bottles each. Three days of competition plus two days of practice.
18000 / 5 = 3600
3600 / 360 = 10
10 per person per day average as you say Si.
Imagine not budgeting that correctly!
