James- Not a forensic deployment Doctor, nor do I play one on TV....but!
1) 3 ft deployment cord seems short-if the charge went off and the line went taunt before the chute came out, you chute is mounted too low on your harness. Try moving your chute up towards the NC a little more (on the next one!) If it was hot outside- see if your NC slides in and off without binding. You also may have used too much wadding. Remember the ejection charge will take the easy way out-including thru the nozzle if the other way is blocked.
2) You don't say what size BT you're using. If it's a 4" tube 24 inches long-yeah-you mite have a problem with too little ejection charge.

I'm usually left holding the bag. If I got a Right bag, maybe it would be better.
Why is it a launch lug? They are usually too small to carry your rocket to the pad with.
Why do I need an altimeter that talks back to me? I can get that at home.
