The developing values in the DVATool do not always match those in the Market Profile chart in eSignal. One of the reasons that this might be is because of a problem with eSignal's Market Profile chart. Here is an image showing the eSignal MP chart with a lower print in the E bracket than the low of day. eSignal are aware of this problem and are working on it. Anyway, this is probably the reason that the DVATool values don't exactly match those of the eSignal MP

values.
