  The Dae$\delta$alus DIC compact cyclotron is proposed to achieve an extracted
current of 5 mA of singly-charged hydrogen molecules, even though unlike other
compact cyclotrons, the extraction is not by stripping. The authors of the
proposal consistently use perveance as a scaling argument that such high
current is possible. The argument is shown to be incorrect and a realistic
limit is calculated. This limit is likely about 0.2 mA and certainly no higher
than 0.5 mA.
