Index vs. course handicap
Your handicap index measures potential ability on a standard fictional course with slope 113. Real courses are harder or easier, so the course handicap rescales the index by the tee's slope rating: index 12.5 from tees sloping 125 plays as about 14. A higher slope means the course plays tougher for higher-handicap players, so you receive more strokes.
What the target score means
Adding the course handicap to the course rating estimates the score of a golfer playing exactly to their ability from those tees. Shooting at or under that number in a counting round tends to lower your index; the handicap system's best-8-of-20 averaging means one great or terrible round moves it only gently.

Why is my course handicap different from my index?
Because the tees you are playing have a slope above or below 113. Tougher-than-average slopes add strokes; gentler ones subtract them.
Does this follow the World Handicap System?
The core conversion (index × slope ÷ 113) matches the WHS. Playing-condition calculations and daily course-rating adjustments are applied by your club’s software and are not modeled here.
