I noticed the two-year rule while adding the snippet, when I thought the
rule was five years, when it was only customs.

So, I split the series in steps, so that we could at least abide by the
established usage of dropping 5-year old entries, and then catch up to
the rule.

I am OK with making the rule '5 years', since that's what I thought it
was.

I'll resend an updated series.

Yann E. MORIN.
