Ok, but isn't detonation more likely to lead to pre-ignition, than pre-ignition to detonation as you previously posted? Pre-ignition used to be quite common in cars when you could buy various star rated fuels and spark plug technology wasn't so good. You KNOW! when you get pre-ignition and can't ignor it. So how would you go from that to the much milder and less noticable detonation?
Sorry ... I'm getting a bit off topic here, and only really being a bit pedantic, but it's hard to resist (although I'm probably wrong) lol
