What happens if the data collection of a URL would exceed the maximum review limit?

Once you specify a maximum number of reviews, crawling stops after these, for example, 2500 comments, whereby it goes backward from today's date.  

When you enter a limit of 2500 reviews and set the 'From Date' to 1.1.2022, it crawls the comments starting from today until 2500 is reached. This means that it will possibly stop before 1.1.2022.
