I have the data from the info box in my reviews and all the logfiles. The table uses the logfiles for all the capacity values, because the info box did not include the high currents or capacity at a specific voltage.

Length is based on button top and protection, i.e. if you know you want a protected button top you already have defined the length (Mostly).
That is also the reason I did not include length, because I already have button top and protection columns.
