I am a rank novice at aikido and cannot speak to the effectiveness of the technique at face value, but my fiancee trained in Ryukyu Kenpo with a teacher who specialized in applied pressure point techniques, and she mentioned that a flurry of blows like that could be used to deliver strikes to a series of pressure points to achieve one effect or another. In such a case the force you deliver would be secondary to the precision of the strike and your use of ki.
Just don't ask me to attempt to replicate it.
