I think ERG mode makes long intervals much harder. The ERG resistance is relentless, you can't let up for a few seconds like you can outdoors on a "dumb" trainer. I always have a hard time keeping my cadence up for long ERG intervals, and once you cadence starts dropping it just gets that much harder.
