Fdb97531 is the 8 ball version of the infamous 7 ball siteswap db97531. Each of the 8 crossing throws is lower than the last so that the balls are caught in the reverse order. The first throw (a "15") should be four times as high as the basic pattern, and the balls should all peak at about the same time.
