core.borrow_rates, the accrued snapshot series. The percentile is the house midrank - (below + half the ties) / n - over one reading per ET day, computed in SQL and NULL below its floor. Fee rates sit on a general-collateral floor, so ties are the common case and the midrank is what keeps a floor reading from reading as the minimum.
