More Compelling Evidence for Graduated Betting Scales

Record on 3x plays (not including tonight) since Week 4: 14-12-2 (53.57%)
Record on 2x plays since Week 4: 43-38-1 (53.05%)

Both profitable, barely. Hardly any difference between them. What was I doing differently last year when my big plays were hitting at such an incredible clip? Is this really all variance?
