That's kind of why I like it. It's a very simple test that clearly shows LSA effects on power. There may be problems with it. But it does clearly illustrate what affect a change in LSA will usually have.
Exactly. If you look at a that test it will show you the typical direction an LSA change will go. But I stand by my original statement that LSA should be based on events. Looking at the cam in that Crane test, it looks to me like a single pattern cam on a 108 would have beat then all, all over. So it's more important to get the right LSA than to just pick an LSA out of thin air, or because you want your idle to sound a certain way etc.
