What is the actual likely hood of this then. If you had 16 caps in series
without bleeders and applied a resistive short across them, is it a god
given fact some will still hold a charge?


yes.. the capacitance tolerance isn't all that tight.

If you had matched capacitors, probably not as big an issue.


If so how much percentage wise is realistically likely, and more to the
point what causes it? Slight differences in their internal losses between
individual caps, or what.

It's the capacitance tolerance that's the issue.

"Where it gets tricky is when you are discharging a series string of
capacitors, because shorting the ends of the string does not guarantee that
the components of the string are at zero volts, just that the sum is zero.
You have to do it in stages.. ground one junction with the discharge stick,
hook on a cliplead.  Ground the next junction, hook on a cliplead, etc."
