Case contract

Rotisserie categories HR and SB rank high-to-low; ERA (earned runs x 27 / outs) and WHIP ((walks + hits) x 3 / outs) rank low-to-high using exact ratios. A team with zero outs has no ERA/WHIP and ranks last. With n teams the best rank earns n points and the worst 1; tied teams share the average of the positions they occupy. Return team -> doubled roto points (integers).

Why this case matters

Roto standings aggregate ratios and ties across categories; ratio precision and tie averaging decide league titles.

Sample boundary fixture

This sample comes from the broken implementation of a controlled reproducer.

Boundary fixture	Actual	Expected	Outcome
regression: tie point sharing	`{"R0": 20, "R1": 28, "R2": 26, "R3": 26, "R4": 42, "R5": 42}`	`{"R0": 17, "R1": 26, "R2": 25, "R3": 22, "R4": 39, "R5": 39}`	Failed
