You seem to be being downvoted a bit, not sure if it's your ridiculously boasty first paragraph or your 3 bits of advice.

But if it is your 3 bits of advice, I'm actually going to say that for a certain type of hackathon, those bits of advice actually make perfect sense. So many hackathons are obsessed with judging and prizes, usually based off judges seeing very little in a brief presentation. If you really want to win, your strategy makes sense. While I haven't adapted it wholesale, I've certainly been in situations where I have prioritised technical work by what will play best in the presentation.

Personally tho, I find this a little sad and the atmosphere at these hackathons can be a little rubbish.
