    Design a function for an automated grading system that calculates the total number of valid evaluation combinations when considering only even-numbered groupings of assessment criteria, given a maximum of n criteria. The function should compute this by summing up the number of ways to select criteria pairs at even-numbered positions (0, 2, 4, etc.) from the total n available criteria.
