Reading this thread for the first time I got to Gatsby's comment and thought about asking the same thing as you Melvin. It's thanks to communities like this that botched patients can get a new lease on life.
I actually have two theories on the results of this poll.
1. People who frequent forums and actually learn their stuff will tend to get better results than the majority who just do 5 minutes of "research" (scrolling Instagram) and book the cheapest deal they can
2. However, if your result is bad or botched, you're more likely to join a forum for support afterwards, skewing the poll result.
Anyway that's my 2 cents.
