Agree Cludo, looking at that page, their FAQ and even FB, to see the same quotes that this has 2% sugar while regular has 6-8% which could be either the 3 times or 4 times less answers.
Depends on what you call average i guess, eg. Gatorade is 6% and Powerade is 8% sugar.
Reading Here it suggests "an average sports drink contains about 3–7% sugary carbohydrate" which would make the answer "3 times" definitive haha.. probably other sites with other stats, but I am going with "3 times" to stay in the safe zone.
Can't find a definite answer, anyone else?
