I think you'd find the most of the folks at the SFQ forum would say "Well Yeaaaaah". I won't put words in Chunyi Lin's mouth, but I'll come close, and say that the 15 years isn't necessary to get most of the benefits.
I was at the retreat, and I suspect that most that had not tried meditation before (me included) are using it now. The effects of meditation can be that grand.
Sending love,
