No, not quite. Blocking off 50% of the jets results in close to double the restriction. Given the way that mag-drive pumps work this would equate to maybe 25% less total flow rates, or about a 50% increase in jet velocity.

Mind you, the MD30-RZ was already pushing about 10LPM (~2.65GPM) through the complete system without the restriction plate, so there's not much correlation that could be drawn with Phaestus's results.
