What is the timing of the actual automatic snipe bid? 1 second left, 10 seconds? I would think that some of the failed automatic sniper bids would occur if several, or even just two auto bids occur at the same time. How closely does eBay drill down on bid timing?

I do do my own snipe bidding, but it's pretty rare these days that anything I really want on eBay makes it to the end of an auction at a price I like.
