I just recently made this google doc that lets you enter the points tested so far, and gives you a list of the possibilities for the moon & mars hotspots and the probability of each being the correct one:
You'll have to save a copy to use it (you can just save it to your own Google Drive). And you'll have to give it a few seconds to calculate after entering your test points.
Try it out with the points tested this month:
(-51, 109) 82%
(-69, 71) 99%
(-69, 70) 99%
(-68, 72) 100%
