Well David,

I'm really sorry, but with only fifteen responses so far, I would hardly say that the results could be 'interesting'

Well done for appearing to be a little more honest that 'Student', but nonetheless, your survey also lacks rigour.

Please, please, may I ask would-be-academics to think through and plan their work, to apply appropriate resources (surveymonkey perhaps?), and to make as few assumptions as possible (why should whether I have one or two engines affect the price of fish? I nearly bought a boat a whie ago with three - where would I be now!?).

As someone who makes his living in effective research and accurate investigation, I'll even offer a hand to those who might wish to pursue these lines of enquiry...
