Forecasting Data with Power BI (Logic understanding required)

I want to understand how Confidence interval (level) works in the forecast feature. Basically the logic behind it.

Does it takes Standard Deviation of data and then works on it? and if I have applied the date filters then what happens with the data Samples?


Here is the visual example.  I have filter Sales data from 1/1/2019 onwards. Screenshot (6).pngScreenshot (7).png

@Anonymous  I tried some sample data and applied a filter - it looks like when a filter is applied, it forecasts the range beyond the filter criteria even though data is available. Please see the attached image: PBI Help conf interval.png
