Will new added IP in Bot Filter impact history data?

Hello,

May I have your help to clarify on following question.

Recently, some new IP address are found as bot traffic source, I would like to ask admin to added into Bot Filter.

The question is, if the IP is added let's say today, will all historical data be impacted?

e.g. there are 100K sales leads in total, 1K came from the IP in the past weeks or months, then when I create dashboard to get the data tomorrow, will the number change to 99K?

Thanks.

H
