Crack is shady ?

So here total 53k responses have been recorded and my rank is around 16k. So out of 50k responses my percentile is 70 ? I mean most of the coaching centres online are predicting the percentile to be 85+ which is laughable tbh . But judging from this I don't even think it'll cross 80 now officially. And to put this in context more , last year 21.45 was about 87 percentile and now barely 80 for the same marks ? This year's exam wasn't that easy for sure especially for the percentile to drop by 10 . What is going on ? Itna mass level pe sabne ekdum se itna acha kaise perform kardiya ? I'm genuinely curious tho because I think I'm missing something. Please enlighten me if I'm missing something
