Can't speak to the Saris on Rouvy, but on my Wahoo Kickr on Zwift the key to avoiding the ERG death spiral in any workout, including intervals, is to keep cadence a bit higher than I would do in the real world - essentially to downshift a bit earlier.

If you think of each interval as a hill, get your cadence up (downshifting a gear may help) before you hit the hill. For me on my trainer, anything above 80 rpm keeps me safely away from the death spiral but if I don't increase above that before the interval kicks in, the dip below 80 can be hard to recover from - the death spiral.

Zwift makes it easy to turn ERG mode off, but then the hills on the course drive resistance and that doesn't match what I'm trying to do on the workout.
