I don’t think the triad can the tied to the spider chart in that fashion.
The chart represents points along your power curve (compared to others) starting with Power Sprinter (10 sec power) at 12 o’clock and proceeding clockwise to Triathlete (3+ hr power).
Athlete types fall roughly into quadrants as shown in my mod of the help file chart –
The points on your chart represent what you are better and worse at but also what your training preferences reflect.
Someone with a rounded plot has hard data (literally) to prove their comparative max level at each of those duration points. Someone with a star-like plot (like me) is better at their high points and either weak at the others or doesn’t train or ride hard enough at the other durations to rank higher. This is influenced by your athlete type selection and how often you use Filter to choose a different focus while training.
You can work on a strength or a weakness by targeting a specific focus duration for weeks at a time. You’ll know soon enough if the chart accurately reflects your capabilities once your workouts/rides are testing that duration on a regular basis.
In my case I rarely hammer for any length of time and avoid long interval workouts so my TT quadrant is shrunk to the center. I’m also not overjoyed when longish VO2max orange/reds show up on the recommended list. 
YMMV
