But differences in duration at ~0.010 lift are not obvious to me and I am surprised if differences in duration below 0.010" cause big differences in performance. I can see that the 068 will have longer duration at maybe 0.006" but does that really have a big effect?

All this must be really sensitive!

The point was less about performance and that the 068 while being a small cam would have less DCR for the same SCR and require a lower octane.
