The provided data indicates significant pricing discrepancies in secondary markets, specifically 'Total Corners (1st Half)'. While the raw EV calculations show substantial alpha, the 'Early Alpha' strategy is strictly focused on primary markets due to their higher liquidity, lower variance, and more robust information efficiency. Markets such as 'Total Corners (1st Half)' are considered niche and are prone to higher volatility and less reliable pricing models, making them unsuitable for consistent quantitative edge detection within our framework. The observed divergences, while numerically high, do not represent actionable signals under the strictures of our model.

1. The core principle of the Early Alpha strategy is to identify pricing inefficiencies in main markets (Match Winner, Over/Under 2.5, etc.) where information asymmetry can be exploited. 2. The provided odds comparison data exclusively pertains to 'Total Corners (1st Half)' and 'Corners 1x2' markets. 3. These corner markets are explicitly excluded from our strategy due to their classification as secondary/niche markets, which typically exhibit higher variance, lower liquidity, and are less predictable from a quantitative perspective. 4. Although some EV values appear high, they are derived from markets outside our approved scope and thus cannot be considered valid signals for the Early Alpha strategy. 5. Therefore, no actionable 'back' or 'lay' signal can be generated based on these data points.
