You don't know the absolute numbers and you don't know the real percentages (just the ratios of those who happened to respond to this survey) and yet say that the survey shows there are enough Iyonix users.
It shows no such thing.
Probably about the best that you can get out of it is that there are people who have declared that they have/use a particular machine. It may give the lie to anyone trying to pretend that Omega users don't read Drobe (or even that Omega users don't exist!).
But don't despair! You can still read quite a lot out of the survey and these comments: not what the results actually say but what people wish they said.
