Reasoning
We treated each source as one perspective and mapped their values to a common scale: easy/low/short = 1, moderate = 2, high = 3, steep = 4. Source 1 is mostly low (1), Source 2 indicates a shorter learning curve (mapped to 1), Source 3 favors steep (4), Source 4 indicates easy (1), and Source 5 favors steep (4). We weighted each source by its confidence (0.80, 0.65, 0.80, 0.90, 0.85 respectively) and computed a weighted average of the scores on a 1–4 scale, which comes to about 2.24. This sits closest to moderate, so the canonical value is moderate.
