Three reads, applied in the same order every cycle. The math first, the role balance second, the audit third.
The default is 9.1 credits per slot. Spend more on all-rounders and the bowler slots starve. Spend less and the ceiling drops.
One all-rounder for a small-field contest. Three for a large-field differential play. Two is the default for most surfaces.
Run the credit-cap balance check before the XI locks. The check catches the over-spend before it costs the XI.
Spending 11.5 credits per slot on a slow turner is the most common credit mistake. The deck does not reward it.
