[KS] Going, going, gyeong: but why 10 quadrillion?

Actually, I thought gyeong was 16 zeroes. That's the way my mother taught
me numbers and she was a real math whiz. After man (4 zeroes), everything
goes by 4-zero increments, and in between is the repeated pattern of
sib-X, baik-X, cheon-X.
10,000 is man
100,000 is sib-man
1,000,000 is baik-man
10,000,000 is cheon-man
and then you move on to the new unit of ok:
100,000,000 is ok (8 zereos)
With gyeong, it would be following jo:
jo -- 12 zeroes
sib-jo -- 13 zeroes
baik-jo -- 14 zeroes
cheon-jo -- 15 zeroes
gyeong -- 16 zeroes
after that it's
hae -- 20 zeroes
ja -- 24 zeroes
yang - 28 zeroes
and so on. there are actually lots and lots more names for these huge
numbers, all following the 4-zero increment system with the sib/baik/cheon
My understanding is that gyeong is not really a new number name -- it's
just one of those that didn't get used much and so the general public
didn't know there was a name for such a large number. But perhaps someone
has scholarly information about the Korean number system, rather than just
experience like myself?
This link above is to a thread on Korean number names, with a nice table.
It might not work, though, since I found it through a search and these
links tend to expire.
Also, I had always thought that quadrillion had either 15 zereos (American
short-scale) or 24 zereos (British long-scale).
This link above has a great table with large number names and values in
