Score Comparison Plot:

The following plot shows how this terminal’s scores compare to all other terminals tested.

../_images/windowsterminal_scores_scaled.png

Scaled scores comparison across all metrics (normalized 0-100%)

Final Scaled Score Calculation:

  • Raw Final Score: 72.10% (weighted average: WIDE + NARROW + ZWJ + LANG + VS16 + 0.33 * SRI + 0.33 * SFZ + RI + CAP + 0.5 * GFX + 0.5 * RSC) the categorized ‘average’ absolute support level of this terminal.

    Note

    RSC (Resources) is a composite CPU, memory, and runtime score. RSC is weighted at 0.5 (half as powerful as other metrics). FEAT (Features) is the fraction of notable features supported. GFX (Graphics) scores 100% for modern protocols (iTerm2, Kitty), 50% for legacy only (Sixel, ReGIS), 0% for none.

  • Final Scaled Score: 62.5% (normalized across all terminals tested). Final Scaled scores are normalized (0-100%) relative to all terminals tested
