Well, from the OP, it says to count the seconds from when the game first turns on until you get to "gameworld" (I used the online stopwatch), and that is your delay or something. Then right below that, it says to Synch your clock, soft-reset at the next minute, and catch a pokemon and get a different delay, which are what I posted.'
...Maybe I just shouldn't be doing this when I have such horrible news, but ignore this comment.
No, it doesn't.
Nowhere does it say to actually count them.
It gives a general description of what the numbers mean/where they come from for informational purposes.
In the calibration section it specifically mentions that you will get a range of delays and that this is normal:
Please keep in mind that we go through this Calibration Phase because each person can and probably get slightly different results. If your average range is between 620 and 630 that is fine. It's just your range and what you should use.
