Have you noticed your match hasn't built MVP for some reason? Maybe the MVP tab doesn't show, the numbers are 0.0, or they just seem too low... Well here are the most likely causes.
1. The scorecard is missing crucial information
MVP will calculate as much as it can from the data entered, so most scorecards that meet the minimum criteria will build some MVP for players. However, to get your full MVP points both teams details and scorecard information will need to be entered. That includes balls for each batsman, wickets taken by each bowler, fall of wickets etc.
2. The match does not meet the minimum requirements for MVP to generate
The MVP calculation tries to allow is wide a ranging set of circumstances as possible. However, there are a few requirements a match must meet to build MVP. These are needed to ensure the MVP calculation fits within the data that was used to create it.
The requirements are:

The Match type must be greater than, or equal to, 5 overs in all innings.

At least one player must participate for each team.

No more than 10 wickets can fall in an innings for either team.
If you match fits within the restrictions above you should get MVP tables for your scorecards.
