"Hey I made a beer that's 180 IBUs (calculated)"
For what it is worth, I understand the maximum solubility of iso alpha acid is around the 90 ppm (IBU / EBU) mark, with it being somewhat lower at higher gravities. So there really is no point in trying to get higher than this. And the extraction / conversion efficiency also drops at higher bitterness levels.
