The distances are wrong.
Should be 4/3 longer.
I think I got it fixed.
Mike said 50% and dersu said 4/3. I got an old terraserver image I made for Mike a few years back with UTM 200m grids on it, and opened it as a template in OCAD and flailed around doing math until it all lined up. I'm confident it's 50%.
It took me about 45 minutes of dinking with it to figure it out.
Yeah, that's right. I remember the first leg was listed as 80m and not 90m as I remembered it (incorrectly) when I wrote the above. (I used a low-tech ruler).
