I do not know if you actually fly the ATR. I have more than 6000 hours on it and in my company there are many pilots that land with at least 20% torque. I know that the SOP of the ATR say you have to set idle at 20 fts. but if you land very heavy or with a lot of head wind it is better to land with some power on you enginees.
It is just my opinion.
