what's your question?

It is not a question but a statement.

These are the results using this various methods, is the statement.
In english I wonder if you follow a statement with a question as you have done?

I like to see if the luma detail on the edges has a clean line or a snowy fuzzy line.

I like to see if one encoding method covers up detail that the original didn't, like blothches in the original.
Were the Bloatches made smooth by the encoder, and if they were then did higher bitrates cause the bloatces to reappear?

I like to see if using lsf made detail appear that was not so good in the original.

Why do I like to see these things? because if I am happy the peoples skin does not look blemish free and plastic, and detail that should be seen is seen.
That makes me very happy and so i thought posting this info here would help makeo ther people happy too. :)
