Will 10,000 hours of Vipasanna be enough for Enlightenment?
I think you are coming at this from the wrong place.  Enlightenment isn't something that we add to ourselves.  It's best not to approach meditation as another skill to master or the dharma as another field where we might gain expertise.  It really doesn't make sense to count your practice in hours, days, or years.  Buddhism isn't a transaction - it's an offering that can't be measured by any metric.  Ultimately, there is no upper limit to how much we can sacrifice ourselves.
