Different sources often report volleyball statistics in different ways. Two sites may list different hitting percentages for the same match because they count blocked attacks or free balls differently. Learning to compare sources is a quiet but valuable skill.

What the figure shows

Start with definitions. Does the source count attack errors in the hitting efficiency calculation? Does it include only first-ball attacks or all attacks? How does it grade reception? Small choices like these can change a figure by enough to alter a conclusion.

To see the variety in practice, compare a few pages, with the AzurSlot Casino website - https://casinoazurslot.com/ as one of them. Notice which labels are clear, which are left to the reader, and whether the page says when the data were last updated.

Timing is another factor. Live data may be corrected after a match, so a number noted during play may not agree with the final one. When quoting a figure, say where and when you found it. A screenshot with the time visible settles most later disputes.

When sources do differ, the official federation statistics, where available, are a reasonable tie-breaker, since they tend to follow the published definitions most closely.

Different scouting software is another source of difference. Operators code each contact by hand, so two operators can disagree about what counts as a good pass or a free ball. The differences are usually small, but they are a reason to take all comparisons from a single source.

If betting markets are part of your routine, keep the money side separate from the sport: agree a budget and a time limit before the first serve, and end the session when either one is reached.

If two reliable sources disagree, the difference is itself useful. It usually points to a definition or a data entry issue, and it reminds us that numbers are made by people.

Sources are made by people, and good ones say how they count. Data is a tool for understanding the match, not for forecasting it.
