At video minute 7:08 you will see the addition mistake which results in an incorrect local hour angle and thus ruining the sight reduction before it is started :( Arithmetic #@!%&

Here is a YouTube haversine sight reduction using Nories.

The instructor made a few mistakes. DR Latitude is 19* 42' N (not E). Not sure what was going on with the 35 NM intercept ( I think it was just for a plot demonstration ). The intercept should have been 1.7' toward on an azimuth of 220.2
As you can see it took over 20 minutes to walk through a single sight reduction.
Chichester must have been cursing all the way to Sydney ;-)
------the sight reduction before it is started :(
