The IG seems to be "loosening the reigns" on the ISAT data.

Previously, the IG held that the BTO's were "Golden" (within the 20 microsecond bins), and that the BFO's were "Silver" (within the plus / minus 20 Hz drift window).

Now it seems that the IG may have had a unstated, and unexplained (yet) change of mind, on the "solidity" of the BTO's, in that they are now introducing the possibility of the BTO's being up to 50 microseconds different from the values recorded.



You could say that the BTO's have been downgraded from GOLD to BRONZE.

I await their explanation for this apparent "change of heart".
