in this data sample there are three varying eliptical shapes in the shot, are these marks something that should be classified as something wierd/strange, as i have not seen these examples in the tutorial, and just wanted some clarification on them. Thanks Christopher

Thank you for participating!
You're right that the tutorial doesn't feature these ellipses. You can safely ignore them - they don't need to be marked or acknowledged in any way.
This is mentioned in the FAQ:
Q: What are those colourful circles or dots I see sometimes? - A: They are artifacts from the computer. Ignore them.
This discussion goes into a bit more detail:
Circles or ovals are where the computer guesses a vertex is. It does a quite good job in slice, but terribly in normal and zoom. Feel free to ignore them.
The FAQ is broken down into a quick and simple section, and a more advanced section for more detailed information.
