No worries, I updated my post

Also, for your (and everyone's) information you're rolling using 6d6
X5 which grants an extra success on hits. You should be rolling 6d6
T5 to get the correct roll. If you're using Edge to get exploding dice you'll roll 6d6
O5 (that's the letter O, not the number 0, by the way

).
So, for your first roll you actually scored 5 hits (still impressive):
10d6x5:
7 [10d6x5=3, 4,
5, 3,
5, 2,
6,
6,
5, 2]
Your other two rolls were made correctly, however, so that's good.
As for spending Edge, I won't ever tell you what the thresholds are before you roll, just like I won't tell you if a shot hits or not when I roll defense. If you roll low you get to choose if you want to spend Edge based solely on your gut feeling, not meta-game knowledge. This might be slightly different to what the book says, but I find that it creates a little more tension and makes Edge a more valuable resource.
So, you get to choose if you want to keep the 2 hits, or use Edge to get 6 total.
