You're partly correct... Schedule 3 of the UK Motor Vehicles (Competitions and Trials) Regulations 1969 specifies standard conditions, one of which is a maximum scheduled interval between the first and last car of 3 hours on daylight events, 2 hours at night.

MSUK have the ability to increase that 'where necessary or expedient', but it can also be side-stepped by running categories within the same event on different permits (like WRGB having a 'National' event tagged on the back).

They manage it everywhere else in the world. I don't understand people's aversion to the idea of giving competitors a reasonable gap in dusty conditions on the island of Great Britain.
