I thought the theory of higher octance fuel was that is more resistance to pre-ignition, pinging/knocking - or it burnt more predictably and uniformly.

This means you can more accurately ignite fuel so it goes bang at exactly the right time (which I remember is around 15 ATDC).

So better octance fuel = less need for advance = better "go bang" timing control = more power.

Have I got it right?
