Why 88%?

Every pair starts at 46. Then each letter adds points: E/I (how you hang out): I and E → +6 · S/N (what you talk about): both N → +18 · T/F (how you handle drama): both T → +8 · J/P (who plans): J and P → +10. 46 + 6 + 18 + 8 + 10 = 88.

For comparison, the same two types score 93% in our love-match rule, which rewards opposite E/I and T/F instead.

Both rules are our own design, not an official MBTI product, and personality types are not a science of friendship.
