vandersteen 2ce sig ii listening distance and tilt

hello. it started to bug me... when determining tilt, the manual says "measure the distance from the listening position to the speakers".

if i'm initally set up to have an equilateral triangle consisting of my ears, left speaker, right speaker of 9 feet, what is my "distance from the listening position to the speakers"?

is it: 108" (9ft) or 93.5" (7.8ft)
