Jet,

I started with 11-13* at 8psi on 92oct pump gas with 65psi Fuel pressure. Iat was 115-135*
Had a 78% humidity factor, and was 5mts over sea level.

That achive a good no kR at all.

Maxout at 14* at same conditions, read some kr. So I backed it up.

Of couurse "with the right set up and a lot of octane and cold air you can sky high timming", but my numbers are real world, not fairy tales.
