Right, this is a distillation. You actually get +10 for a correct buzzer answer, and then some bonus questions, which the team can answer. Bonus qs are worth +5 (each), and typically (in my experience) you get about 2 of those. So +20 ish on avg per correct buzz. Combine that with possible loss of points and you get these numbers.

Obviously these are points (net change vs other team), not reward or utility! I equivocated those a bit in this discussion too.

It’s possible for your team to lose five points, thereby giving the other team five points. If the other team loses five points, then you gain five points. Why is it not possible for the other team to lose five points without anything else happening? Where does the asymmetry come from?

Why no (+5)?

It’s

-25 −20 −5 0 20 25.

Why isn’t it

-25 −20 −5 0 5 20 25?

Ah, I see! You’re spot on. Failure to properly proofread—thanks, it’s amended now.
