Myst said:1. Save the Master Ball for your Lati.
2. 1/8192m is the chance. The computer could go horribly against you lick-wise, hence you are not by any means guaranteed a shiny after 8192 pkmn, or else everybody would have at least one on a normal game--with normal time put into it. You may have to wait a very, very long time for one, seeing that, at a rate of 30 pkmn per second, to find 8000, I believe it was somewhere around 68 hours. In other words, do not catch Rayquaza yet. Look around for a much longer time in an area where you would want a shiny if the worst comes. Then, after you have piled ten hours or so, go give Rayquaza a couple soft resets and maybe luck will come your way a bit-more easily...

If it would be per minute, it would be:
(8,192 / 30) / 60 = Approx. 4,5
So it's like 10 hours (cause you won't make the 2 seconds per battle).
