Apparently, to get the Venus Sigil, I must dodge the lightning on the Thunder Plains 200 times without being hit once. Well, I dodged the bolts well over 200 times, but when I checked my record in the travel agency, it acknowledged this but claimed that I had only dodged it them 166 times "consecutively," even though I had never been hit once. So I went back out in the plains and dodged the lightning about 50 more times, but when I went to check my record that time, it said that I had only dodged it 165 times consecutively. So I gave up in disgust.

What exactly was I doing wrong? Does the fact that this is my first time through the plains affect matters?
