ADR state definition change

Hello all,
did anybody noticed a change in the flag AccumulatedDeltaRangeState on data captured using the GnssLogger app? According to the GSA white paper (page 23, table 7), this flag can assume the values (0, 1, 2 or 4). And all was right until a few months ago. Then, starting from January 2019, the flag values changed to 17, 18 and 20. I saw this both on a Xiaomi MI8 and on a Samsung S8.

Our guess is that this flag is the result of a bit shift operation on certain conditions, and that a new condition, non mutually exclusive, corresponding to a shift of 5 bits (16) was added, on top of the previous four.

I was just curious about this change. Any idea about the rationale of this?
