Anyone can open a ticket, you just need to register first (which means
you'll get email for ticket updates, and also reduces the torrent of
spam tickets and comments to a handful a year) - just go to:

http://trac.survex.com/register

I'd encourage people to open tickets, particularly for non-trivial
issues, as it means they won't accidentally get forgotten about.

Not totally - it'd would be clearer to give an example with numbers in,
and what calculations should happen with those numbers.

Currently distances are required, but it's certainly possible to
implement this.

Yeah, that'd be good.  Please open a ticket.
