Im assuming that its the one that explains it with a diagram like this. A normal 10-min traffic sequence would look like this:

To land the DLH would look like this:

A halving of the landing rate would look like this:

Or alternatively this;

Doing full instrument approaches for every aircraft halves the landing rate, making an
individual gap for an individual instrument aircraft should not halve the landing rate, and I didnt see anything in the video to suggest otherwise. Sure, 3 gaps in a busy sequence is still a hit, but its infinitely different to drop to 57 planes in an hour, not the 30 planes in an hour that guy was claiming.
