I believe this was more-or-less fixed by the TNG patch.

However the percentages are not exactly right.  They are additively
cumulative instead of multiplicatively.  For civ2 ruleset this could be
fixed with a complicated set of reqs and nreqs.  For default ruleset we
should just make sure the documentation corresponds to what the effect is.
