I didn't look it up...  Just goes to show I shouldn't be just
trusting my memory! [grin]

Where do you get 120?  A SJ month is defined as 28 days/4 weeks,
so 4 months is 112 days.  Yes, about 1%.


(I find 28-day months really useful, as you have 13 months in a
365/366 day year, and you just make the spare day/days 'year
days', a holiday not in any week or month.  This means the same
date occurs on the same weekday every year, and all sorts of
calculations are a lot easier! I know a number of DMs who run
their campaigns on this basis - one even uses our RW month names,
and sticks an extra month in at the end of the year called
'Yule'! [grin] )

That is one reason that I've tried hard to avoid using 'year', in

any of the SJ spell specs - there is no such thing as an SJ year!

1,000 makes sense.

Maximum over-crowding on a 100tn ship is 1,000, using the 10
people per ton rule.

Imagine 10 people hanging on all over an elven flitter, as it
makes an emergency lift-off from a world!

I tend to err on the side of complex, as a spell can be several
paragraphs these days, which makes them a lot easier to read.  If
you don't put the limit in, you can bet someone will abuse it!
