"So since I'm a newbie and already had one squib, does this mean I have 25 - 30 years to wait before the next one?"
Well. maybe...but it's like living in the 100 year flood plane. If you get washed away on Monday the odds are that you are OK for the next century, but you might get washed away again next monday.
Try to figure out what went wrong...In my case I gave it considerable thought and still have no idea.
