Those were the old rules (before 16 Jun) and a calendar event now has no limit, afaik:

A permanent has a maximum of 30 per day.
It is up to the oraniser how they wish to arrange their event eg sending off riders at intervals in groups of whatever. LEL does just that, and PBP too.
"Why should I be penalised because It enjoy cycling not football?"
What is this penalty of which you speak?
Lots of people couldn't get tickets to a footie match. Why should they be 'penalised' while cyclists can use the roads without even paying road tax? Why should 22 players who can't achieve a goals scored differential be penalised by the mental trauma of a penalty shoot-out for one of the most important moments in their lives? I guess life's just not fair (as my father used to remind us, periodically).
LLEL (1000km) had 33 starters (finish today).
