    Thanks for the response, you are correct, this practice bubble is a bit of a toy.  But if your land locked most of the time, it helps to pass the time.

    Oh yeah, thanks for the class on Lunars back in 2015, I got hooked on this and find it quite addictive.  I've had some fair results, and use my Iphone for assumed Latitude and Longitude, the equations from John Karl's book to calculate Hc and Zn. then uncorrect the latitude and longitude to get my location,.  That's where I run into trouble, hence the practice bubble.  thanks again, have a great day!
