I've gotta say, this little competition has got me pretty interested. Researching deeper into my hobbies is always a good time, and it's one of my favourite things to do when I have the time... hence me spending probably half an hour of research and note-taking so far on this contest. I'm 99% sure I have the answer, after a little bit of thinking and googling, but one thing is giving me doubts - you said I only got 3 correct on my attempt, but based off my current thinking, I'm pretty sure I got 4/5.
Anyways, I'll PM you my guess and my reasoning tomorrow, can't be bothered now, and I'm not too fussed about winning - my competitive spirit just wants me to be right ?
Cheers!
