Pardon the ignorance, but if I change the model instead of 9 points to less; do I need to change all averages?
Do I need to do so when I only have three critical points or categories?

If we have inputs only then how can we create a matrix for the antecedent and consequent part in a rulebase?

Like what the author said, the Representation is intuitive to understand. The software is useful!
