Why 76%?

2 and 11 are both in the ground family (2, 4, 8). 11 is a master number, so it is matched as its root, 2. The same root number twice starts at 76. The nudge comes from the roots: 2 + 2 = 4, which leaves 1 when divided by 3, so the nudge is 0. 76 + 0 = 76.

Out of the 78 possible pairings, 21 score higher than this one. Rarity: 4.6% of birthdays from 1950 to 2009 give 2 and 6.5% give 11, so about 1 in 166 random pairs of birthdays land on exactly this pair.

The rule is our own design, not a numerologist's chart, and numerology is not a science.
