In any case, the "system" can use many techniques to "smooth" the data that is provided the main FCS confuser. Talk with me about data reduction on a test system that had crappy electrical wiring, and took us weeks to figure out the problem.
Somebody has suggested the curbs were Excel made. We know from BEA that "void" AOA values are not "transmitted". So, in the BB memories, they are absent or replaced by a non numeric value. With Excel graphes, if you don't tick the option "ignore absent values", they are considered as zero. Perhaps it is simply that?
