Correcting some typos, and deletes that didn't happen:
1) "Personal experience" not Personal expereience.
2) "So that's not very interesting a very interesting post" should read:
"So that's not very interesting post"
3) "200s betwenn 39-31s" should read
200s betwenn 29-31s
4) necessary, not neceessary
I should be a little more fanatical about rereading what i write for spelling and grammar.
Sorry to have taken an extra post for corrections.
