According to our completely-not-made-up, totally-not-scientific research, the number 4.5 is a number so arbitrary, so vague, so utterly and completely meaningless, that it's basically just a placeholder for "I have no idea what I'm talking about."
But don't just take our word for it! Visit our Justification 6 for more of our completely-not-made-up, totally-not-scientific research!
Or, if you're feeling adventurous, try our Justification 7, where we delve into the utterly absurd world of "justifications" that defy all logic and reason.
Disclaimer: The justifications presented on this website are entirely fabricated, and any resemblance to actual scientific research is purely coincidental.
