By the title I thought the next line would be they all went into a bar.
These are thing that I need to pay more attention to when I am out shooting, Thank you.

No worries. There are a lot of acronyms in photography, much as any other technical subject.
ETTR - Expose To The Right
EBTR - Expose Beyond The Right
My apologies for not putting those definitions in the article. I'm not a fan of acronyms and usually put the definition in the first time I use the term.

Did I get my his right- the histogram on pics 2 is more to the left and pics 5 the histogram was corrected to to the left?

That is the basic idea. The idea of exposing to the right is to meter the brightest part of the scene and then adjust the exposure settings of the camera to add additional exposure than what is indicated. The additional amount is based on the particular sensor in the camera being used. The only way to determine that is by testing.
The entire idea is to prevent overexposing the bright areas of the scene. Measuring those areas will indicate an exposure that will place them in Zone V, middle gray. So, by adding exposure we can control the brightness in the final image and prevent blowing the highlights.
Since "the right" is the right of the in-camera jpg, there is a more room available if exposing using RAW for the capture. How much? That is determined by testing. If applied correctly, the placement of the highlights can be done rather precisely.
There are some very good articles on the web if you search for the term ETTR.

To my eyes, the last one is actually the best of all of them. Am I seeing something incorrectly? It more closely resembles the metering off the grey, but actually seems to have more detail. I would assume, then, from my observation, that using the auto metering in the camera would offer a better result.

AzPicLady, The last one was actually processed. Thus, it may look slightly better than the others, which were SOOC. Thanks for taking a look and leaving a comment. Actually, using ETTR/EBTR techniques rendered a better image. The average metering gets close, but the ETTR/EBTR image renders better control.

So now my question has to be how do I get my camera to do this?
