99% is not an error! It is a flag that an error could not be calculated.
It needs at least 4 (better 5) independent runs to calculate a standard
deviation. If the number of runs is less than 4, the FLUKA analysis
tools print 99%. That number has no meaning, it is only a code for
"error not calculable"
