While I did not get the ones I wanted most this time around, I did get in twice in a row now. The only thing I do is use Gmail. I keep two browser pages open next to each other, one with the timer, the other one with gmail. I make sure to have the one with gmail selected, (otherwise I would have to click twice, once for selection, second to send the mail), and just send when the timer hits 0. I do not actually wait to see the zero. I time it by counting down and the moment the switch occurs is when I press send.
Though even after all that, I am still quite convinced most of it is random luck.
