Alright. Well, save in front of Virizion. Then, hit your second, and capture it right away. Make sure you DON'T have a syncher in front, to make it easier to find your starting frame. Capture it 3 times, the first time, you don't do any PID Frame advancements, the second time, you use Chatter Once, and for the last one you use Chatter Twice. If you did it right, you got the right IV spread 3 times in a row, with 3 different natures. Find the nature of your first attempt, it should be around PID frame 40-60. Then check if the second and third match as well, and viola, you just found yourself your starting frame. :)
But, doing more then 700 Chatter's is pretty much, though
