I don't mean to come across as combative, and I apologise if I do, but if you don't mind me politely asking; why exactly have you come to a roller coaster forum to ask this question? I understand the need to conduct market analysis, but surely there are many far more representative samples you could get info from? Roller coaster enthusiasts alone are not going to be a particularly representative sample of wider society, and CoasterForce also probably provides a far smaller sample size than some other places where you could conduct analysis.
Nonetheless, I wish you well with whatever you're doing!
