When rain interrupts a limited-overs match, the target is revised by the DLS (Duckworth-Lewis-Stern) method. Here's the idea without the maths degree.
Two resources: overs and wickets
DLS treats a batting side as having two resources — overs remaining and wickets in hand. Lose overs to rain and you've lost resource; the target is adjusted to be fair for the resource each side actually had.
A simple example
Team A makes 300 in 50 overs. Rain cuts Team B to 40 overs. Team B hasn't lost wickets yet but has fewer overs, so DLS sets a par target above a simple 80% of 300 — because wickets in hand are worth a lot. The revised target might be around 245–255 depending on the tables.
Par score during the chase
While Team B bats, there's a live par score — if they're above it when rain ends the game, they win; below it, they lose. That's why you'll see "Team B need X, par is Y" on the scorecard.
Why it matters
A rain cloud can swing a match in minutes. ALLPANELEXCH shows the DLS par alongside the live score so you always know who's actually ahead.
