I guess what I am trying to get at is that, if done properly in a refined manner, the "replay" feature will mimic TC by maintaining resistance of the wire at the determined point by varying current and voltage as needed. In effect it is a sort of temperature controlled mode but without the wire type being specified it isn't really TC either, I guess. The chip could record the increase in resistance as power is applied, store that information, then calculate a relative TCR. Again, without the wire type being specified it's just a relative number. In a "perfect world" situation the readings could be compared to a set of know wire type to determine the most likely wire type. If the wire is specified, those readings could be compared and adjustments made to the TCR as needed. Whether or not all that processing power is on the chip, of even necessary, is a whole other question. But doing whatever they are doing does provide a level of control that, if it works as well as EVolv TC does, will be fairly accurate and repeatable just not real TC unless you're already in TC mode.
