Why does cron @daily @weekly @monthly run at different intervals of minutes?

Question

Task Schedulers

Standard crown configuration. Can you please tell me why there is an offset in minutes?
17 * * * * root cd / && run-parts --report /etc/cron.hourly
25 6 * * * root test -x /usr/sbin/anacron || ( cd / && run-parts --report /etc/cron.daily )
47 6 * * 7 root test -x /usr/sbin/anacron || ( cd / && run-parts --report /etc/cron.weekly )
52 6 1 * * root test -x /usr/sbin/anacron || ( cd / && run-parts --report /etc/cron.monthly )

Answer 1

So that all the crowns do not come at the same time and the server is not laid down for you. This is a common practice of "smearing" the load over time.
