Also to add more information, the software would request data from the dividend history page once a month at most, for between 100-2000 stocks to find the best projected dividend growth stocks based on estimates.

That means it would basically open the dividend history page for different stocks 1 time a month, up to 2000 times in total per month (but probably more likely ~500 or less times per quarter - equivalent to a regular website visitor going to 500 pages in a quarter)
