That ±11 is your stress-fit, how steady you each run under pressure, the single biggest factor in whether couples last. It's the one thing four letters can't show.

You share solid common ground and differ where it stays interesting. The deciding piece is one we can't see yet.
Real psychology, real nuance. So we show a range, never a fake-precise number. The width is exactly what your four letters can't reach.
Friends ride out each other's off days more easily, so steadiness counts for less here, and the band sits tighter than in love.
At work you lean on each other's habits more than each other's moods, so steadiness barely moves the number. The band is narrow, so this read is already close to final.
Why a range?
The band shrinks as we learn more. Right now we only know your four letters.
How it actually goes
Why a partner's warmth, steadiness and reliability, and not whether your types match? Across about 3,800 couples, those three predicted how happy people stayed; how well two types matched barely did. (Malouff 2010.)
Take the test → see your matchTakes 4 minutes. It pins your half of the band, the steadiness that actually predicts it, and saves your card.
