In preparation for PacCup 2016 I was creating a sail chart for the SC50 I will be navigating in.  Yes, I know, should have been done a long time ago, etc, etc.  but this was not up to me.  In any case, this is a new boat to me and I'm working with the raw data provided.  I used the provided sail selection data to create the required Expedition sail chart text file but when loading this the wind angle at the top would not show up.  After much experimenting and comparing with the reference sailchart text file that comes with Expedition I got the TWA numbers to show up at the top.  This required changing every wind angle on the text file to be a multiple of 5 or 10.  Expedition did not seem to care about the increment in TWS but any increment in TWA not a multiple of 5 or 10 would cause the TWA on top of the sail chart display to disappear.  What gives?
