A slower tempo also changes the duration
When you want to play Line Dance music more slowly, you change more than just the time between steps. A complete sequence also takes longer. At a setting of 0.95×, the recording plays at 95 percent of its original tempo. This is one possible first test level, not a training recommendation that suits everyone.
The same number of repetitions at a changed tempo is not a comparison with equal dance time. For your first test, a short excerpt of the same length works well: for example, one minute each, even if the timer ends in the middle of the sequence. Start both times at the same point in the recording and keep your step size and arm movements as similar as possible.
Slower movements may feel easier, but they don't have to. If you use the extra time to bend lower, take bigger steps, or balance on one leg for longer, you change several things at once. Fatigue from the first test can also skew the second. So rest before comparing until you feel about the same as you did at the start.
The article on Quickstep speed also explains how practice music changes movement patterns. The same principle applies to increasing the volume of your dancing later: increase your dance load gradually. Assess one change first, then make the next.
