Well, given that the most likely scenario for getting into VRS on approach when you think your airspeed is sufficient, is because you're in a tailwind, doing this simulation with a good amount of forward speed was correct for that type of situation.
You are confusing groundspeed with airspeed chum. If you fly a downwind approach without realising it (unless the wind is very light and variable) you shouldn't be in the cockpit. If you know you are downwind you take extra care to avoid letting a high RoD develop.
Whether you believe in the Vuichard technique or not, learn how not to get in the situation and learn to identify the early stages of onset.
Prevention is always better than cure.
