[Forecast vs. Actual](https://docs.datarobot.com/en/docs/classic-ui/modeling/analyze-models/evaluate/fore-act.html) helps you to answer what, for your needs, is the best distance to predict. Forecasting out only one day may provide the best results, but it may not be the most actionable for your business. Forecasting the next three days out, however, may provide relatively good accuracy and give your business time to react to the information provided. If the experiment included calendar data, those events are displayed on this chart, providing insight into the effects of those events. Note that series-based experiments are sometimes [compute-on-demand](https://docs.datarobot.com/en/docs/workbench/nxt-workbench/experiments/experiment-insights/aot.html#display-by-series), depending on projected space and memory requirements.
