Does this prove David Vizard's 128 lsa formula ?

Exactly. "Willing to lose" suggests that more is better. It's not. Timing is about what the engine wants under that specific condition. The only time less advance is a "loss" is when an engine is was designed to run with a fuel that was more knock resistant than what is actually being used. We see the newer engines and even heads alone are more efficient and so less advance is needed under full throttle. That's not a loss.

The question was based on that to run more cr than people are generally willing to run eg 12:1 instead of 10:1 that you would have to run less than ideal timing cause of pump gas. (Wasn’t my assertion)

Say for 12:1 ideal timing was 33 degrees how much less than ideal timing would you run (for pump gas) that it becomes we’re it wasn’t worth going to 12:1, eg. 32,31,30,29,28 etc..

If I remember right that was the basic question.
