Seeder/Peers Figures Updating?

how often are the trackers scraped? i just tried downloading some of the
universe episodes and 100+ peers appear, but during the download only maybe 4
seeders and 10 to 20 leechers appear.

is there a way to get a more accurate figure?

only the latest 100 torrents get scraped on our site, and that is updated every
5-10 mins
