The point I was trying to make, is that a partial power climb can benefit from a more conservative advance. I know that SDS has an LOP switch for cruise, which means that you have a more conservative advance curve until the pilot determines cruise configuration and switches to cruise mode. I was thinking that this can be automated, but I like the idea of pilot control.
Perhaps this idea is more about the limitations of competing systems than the SDS system.

Yes, the other EIs have no way to determine when you are LOP where more advance is required to achieve PCP at the optimal crank angle so as you say, they often have too much advance ROP to have optimized timing LOP.
We just had a customer switch from one other EI brand to the CPI-2 because he was fighting high CHTs ever since he installed it. His CHTs dropped substantially and he picked up 6 knots I believe showing that the canned curves were too far advanced, costing power and giving him high CHTs. This is a common complaint we hear.
