What price failure ?    More time is wasted by NOT using sufficient
bypass caps than is saved by not designing them in (in small
production runs). It is really hard to OVERDO the caps, unless the
power supply is unable to start because of the peak current :^P

Which happens, my system reached the point where the power supply was
adequete for steady stae use, but couldn't power up the system. I had
to unplug one row of modules from the power chain until the system
powered up. When all the other modules had charge their caps, the last
chain got pluged in. I finally solved that problem by putting in an
upgraded power supply - two modules wide with 3X the current
capability.
