Sort of failed:

In all 3 cases(including previous post) it seems that the sweet zone is 45-47LOD. The IGN seems to fall into place when the LOD is achieved. You have obviously noticed that SHM is not as easy as it seems especially while trying to document it!

Viewing the SGII through the camera LCD sucks! Oh, I was able to achieve 62.6mpg to work today
