I wouldn't know, exactly. I just know it was deeper than the 2oz with the same lead.
It worked well, so I just duplicated it when I put it back out....and, it caught more fish. Now, it's part of the line up to start. Two lines with 2oz and two lines with the 3 oz, when I'm only running 4 boards.
Sometimes, you just need to experiment a little. If it works, duplicate it. If it doesn't, change it.
