Concerning your F1 quiz & probably more later on ...
Before the first response (with answers) I initially thought (and was going to suggest) when persons taking part, they should email their answers to you.
Maybe next time and in a timeframe with persons responding.
Btw (me craftily using others' responses) was it a disqualification for a prize ..

Mind you, not that I was looking out for ... but rather some early morning thoughts
