The trace path files are dirtier than what's described in the Data Section.

\n
    \n
  1. Some files include an additional feature for the sensor data. This feature is probably accuracy.
    2. \n
  2. Some files include an additional feature for ibeacon. This seems to be irregular. I don't really know its origin.
    3. \n
  3. Some files lack the end of line character (This was already said in the Data Section).
    4. \n
\n

Are there any other things you noticed? Knowing all the irregularities would help reading the data reliably.

I am still unsure if the last column in sensor data is accuracy. If its accuracy ,is it 2%,3%,3%,3% respective to above records.

The last column is indeed the accuracy.
