.4bps on a sunny day. The junction between the faster to slower modules can be
regulated with what I call "leaky bucket" modules to regulate/throttle the ball
flow from faster modules to slower ones.

I'm not sure this is the way to do things... I don't want to seem cruel or
anything (but I will be blunt), but this module of yours doesn't meet the GBC
spec of 1 bps.  It is your responsibility as a builder to make it fit the spec,
not change the layout to meet your module's ability.  It isn't terribly
difficult to split the ball stream within a single GBC module.  I once had a 48
x 48 module that split the ball stream into 4 separate streams for this very
purpose.  If your module as is can't meet the 1bps spec, then something in the
module needs to be changed.  The idea of the spec was so that EVERY module could
be put ANYWHERE in the GBC and it would all work.  In the past, this has been
bent so that modules that can't handle large batches are not placed downstream
of a batch- output module, but overall throughput was still 1bps.

In my mind, reliability is a completely different issue.  Reliability specs
aren't specifically laid out in the GBC spec (unless that has changed since I
last looked at them), and as Rafe pointed out, getting very high reliability
requires LOTS of testing, which some simply do not have the resources for.  It
is perfectly okay to split the GBC into high reliability and lower reliability
zones.

Just my $.02
