Narrative:

I was working radar flight data when it was brought to me that aircraft X was coming into clt via the PARQR3 in a south configuration at FL210. I went and observed the aircraft cross ncoma at FL180 showing 360 kts. This was most likely pilot error; but there is nothing we can do at that point to help. With our arrival windows being so drastic it allows both the pilots and center controllers to utilize the top of the window if they choose; but farther down the road crossing restrictions are not made putting clt controllers at the mercy of the opd. The arrival windows need to be changed to allow any and all aircraft to make the descent profiles. It also holds the center accountable to make sure they put the aircraft in a workable position for approach.

Title: A TRACON Controller reported aircraft on an RNAV STAR are routinely too high and fast to efficiently sequence even while complying with the published crossing restrictions.
