That's about right.
The area of inlet for a 1/4 nozzle is 31.67 mm^2. Take out the center fins (1.5 by 6.35 twice, minus 1.5^2)...31.67-16.8 is... about 15 mm^2 for inlet area (minus those tiny tips). That's about the equivalent area to a 3/16 nozzle, but it needs to be recalculated for its hydraulic equivalent: it's actually more restrictive than a round nozzle.
17/32 is another good nozzle size. Anything 3/8 or less would also work well, theoretically, but anything in between is a no-no:shrug: (I charted everything in 1/32 increments)
