Other snipe systems simply send through test communications to ebay's server just prior to a snipe and then measure the ebay response time. Its not rocket science.
While it is true that on the few occasions that I have missed a snipe I have not been happy, giving my competitors a 10 second period to outbid my snipe is far worse, as this causes losses with far more frequency than an occasional missed snipe. In asking how AS adjusts the snipe time I don't need to see the AS programming code. Just a description of what AS does prior to bidding. Not necessary to reveal trade secrets in the course of describing the bid sequence.
The AS marketing slogan is:
"Bid at the last second, automatically"
There is no mention in the AS documentation of any adjustments made to the snipe time by AS.
What I do find are statements like this:
"Place your bid exactly when you want … seconds before the auction closes."
