RIFLE classification is inaccurate in many instances

I think the classification into risk, injury,failure is not very useful unless you specify a timeperiod over which it happened . For instance a person with failure can have a creatinine of 1.5 and still be considered to be in the risk category until enough time has passed for the creatinine to rise.Same way, what about RPGN where s.creatinne could rise over weeks to months?How can you unify that with ATN which is what the classification system is probably meant for?Traditionally ARF includede all forms of acute rise in creatinine including ATN as well as glomerular diseases.
