Support power (measured index)
The SS/S/A/B grade and the 0-100 score are a MEASURED index built from the game's own master data: every effect the card has at max level, summed across 4 axes (flat stat · stat growth rate · lesson SP rate · stamina and P-points), normalised within the SAME rarity with equal weights. This is NOT a community meta tier — it is a yardstick for comparing cards against each other.
Level-up curve
