1. You don't have a decent a sense of time as you think.

If you try to keep track of time, you lose concentration on the card. Your brain can't do both very efficiently. Or at least mine can't. So, yes, I am looking for both the exact time, and for me to be able to concentrate completely on the card and not worry about the time.
2. I understand that. Actually, if it automatically flipped the card, that would probably be the best thing; then it's just a single swipe wrong to go to the next card.
Another thought that occurred to me is a complete deck time (in addition to the above per card time). That is, you have two minutes total to get through the deck, and any you don't get to are marked as wrong.
Thanks!
