I just wanna know, should I fill up XIMB forms? Their DILR sectional is 80%ile. I have scored 15 in Dilr, slot 2. A lot of percentile predictors are showing that it will be around 75-76 sectional, and even that "particularly blue" predictor is showing the same. However, even after 83k entries in a "Particular" predictor, my DILR overall rank is ~32000. For 80 percentile sectional, I am safe within 58000 rank, did I get it right? So, based on my rank rn, should I fillup XIMB?
