Since the target audience is 'people who dance to the same music from ~midnight to sunrise', the ability to sustain a steady pace over that period matters the same way it would for a marathon runner or similar. I haven't gone racing in a while but goa parties used to have a pretty consistent cycle of warmup for an hour, take off over an hour, full-on for 4-6 urs depending on the time of year, then the sun comes up and it would switch to 'sloa', basically the same musical flavor but coasting down to a walking pace.
