According to the article, how does the intermittent recovery test differ from the intermittent endurance test?

if I'm not mistaking the answer is

The intermittent recovery test differs from the intermittent endurance test in that, instead of using a twenty-two and a half meter long strip of floor space, it uses twenty-five meters. The extra two and a half meters are added to the shorter section, making a five-meter section for the active break period.

One of the main differences of an intermittent recovery test as compared to intermittent endurance test is that: subjects of these intermittent tests have different duration of active breaks. To add up, 5 seconds is only allocated for the endurance test, while a higher 10 seconds for the recovery test.
