   ** Nonsense and one of the stupidest myths out.   
      
   Charging current pulses hardly vary with larger than usual filter C.   
      
   Because as you increase C, the voltage drop to be topped up each cycle gets   
   smaller and smaller -  meaning the exact same charging current pulse does   
   the job.
