Looking at the first example, the distance plotted from own ship to M1 is 280T and 16500 yards. M2 shows 330T & 14000 yards. It would seem that this plot does not take into account the movement of Own ship for 25 minutes at 10K.

I did not figure that the sub stopped dead when it made the first observation.......

When I plotted it with movement of the own ship, the contact's course came out at 084T, but I can't seem to figure out how to calculate the intercept course and speed.
