Explanation of Symbols
| Symbol | MEANING |
|---|---|
| = | No performance change (confidence interval within ±1%) |
| (=) | Probably no performance change (confidence interval within ±2%) |
| (+)/(-) | Very small performance improvement/degradation (≤1%) |
| +/- | Small performance improvement/degradation (≤5%) |
| ++/-- | Large performance improvement/degradation (≤10%) |
| +++/--- | Very large performance improvement/degradation (>10%) |
| ? | Probably no change, but quite large uncertainty (confidence interval with ±5%) |
| ?? | Unclear result, very large uncertainty (±10%) |
| ??? | Something unexpected… |
