#### How quickly do user profiles move through Journeys?

It may take up to five minutes for a user profile to enter each step of a Journey, including the entry condition. For Journey steps that reference a batch audience or SQL trait, Journeys processes user profiles at the same rate as the audience or trait computation. Visit the Engage docs to [learn more about compute times](/docs/engage/audiences/#understanding-compute-times).

#### How can I ensure consistent user evaluation in Journey entry conditions that use historical data?

When you publish a journey, the entry step begins evaluating users in real time while the historical data backfill runs separately. If a user's events or traits span both real-time and historical data, they might qualify for the journey immediately, even if their full historical data would have disqualified them.

To prevent inconsistencies, you can manually create an audience that includes the same conditions as the journey's entry step. This ensures that it evaluates both real-time and historical data. You can then use this pre-built audience as the journey's entry condition. This approach guarantees that Segment evaluates users consistently across both data sources.
