Hello Dylan,
Thank you for your question about your snipes. We buffer all snipes by the average delay we experience with eBay at the time, which is usually less than two seconds. But lately, it's more spread out, so we've had to change it to the MAX delay, not the average delay, which will give it the extra half second or so it needs.
That said, I looked at your bid history. For you, I'd suggest no earlier than 3 to 5 seconds. This is because most of the items you bid on are popular and you encounter a lot of tie situations. In those cases you lose because your bid came in after theirs. It has to do with the minimum bid increment.
The one-second delay is intended for very low price items with low competition. If you use 3 to 5 seconds across the board, you will win more often because your bid comes in earlier, but still late enough so someone can't react to your snipe.
I hope this has been explained to your satisfaction. If not, please tell me how we can improve.
