Single-match mode calculates NRR for one game. Tournament mode aggregates all runs and overs across the season, which is how ICC and domestic boards compute standings.
The full quota of overs per innings. Used only when applying the "bowled out" rule - if the bowling side takes all 10 wickets before the quota is reached, the full quota replaces actual overs in the NRR denominator.
Tick this if your team lost all 10 wickets before the quota was reached. The NRR formula then uses the full over quota (e.g. 50) instead of the actual overs faced.
Tick this if you dismissed the opposition before their full quota. The NRR formula then uses the full over quota for the denominator of the conceded run rate.
