Timing Curve on 360 in an RV

I didn't follow the "start with setting your curve at 26* at 2800, and then change it to be these other settings." Why do one and then the other?

The info from AJ is to set TWO different slopes on the advance curve... one from idle to 2800 RPM and a slower slope from 2800 to 3400. But from your descriptions of the computer settings, you can only set one slope on the curve, from idle to the end RPM (Unless you can choose in an earlier menu to have 2 slopes in the curve).
