Column states correspond to the benchmark state while rows denote the state of the FCD AID. Underlined values are false positives while values in bold and italic are false negatives. Values in bold represent hard misses while italic values denote soft misses. Reported results are the percentages of time spent in each of the (loop AID, FCD AID) state combinations throughout the study period over all loops.
