I admire your recent enthusiasm and posting to the forum. Allow me to share my thoughts....
I personally like principle 7 -- "working software it the primary measure of progress"
On another note, Scrum no longer (officially) uses "commitment" -- instead, the word is forecast.
Velocity is also not a part of Scrum anymore. I've worked with Teams that use it, as well as a Team that didn't and did quite well.
If you're open to elaborating what you wrote, with examples or a narrative, I'm sure there will be a lot of curiosity, along with great dialogue!
