Here's a thought.
In the case of preparing a document to be read by anyone that you want to impress, try to work on your writing skills as well as knowing your subject matter.
and I've came to a grinding halt!
You used "I've" and that being a contraction of "I have" which is past tense, should not be followed by came which is also past tense.
Using "I came", "I've come" or "I'm now at" would be less inclined to have some of your audience (the educated section) thinking that you're a plonker.
