Whatever 2 degs of overlap does to change your idle. If you have very little it's a big change if you have a lot of overlap it's a small change.

You're going from 12 to 14 degrees at .050, so it probably won't be that noticeable.

It doesn't turn RPM to use the duration at hand due to the lobes being hard to control. Keep searching.
