when IAM resets after every drive cycle, you have no long term knock correction. Setting the initial value to a safe number results in a delay in getting full performance every time you drive the car. Setting it to 1 could result in excessive knock everytime you drive the car if you get bad or slightly worse gas than normal or weather changes etc.
Would you really want long term global correction in a country where fuel quality and options vary so greatly? I think i'd prefer it to figure it out on a per-tank basis, especially if it were forced induction, although me being paranoid i'd rather just map it safe without any adaptive advance into the unknown.
