Cross checking epicenter hypothesis by random dares

 

As one of my friend suggested to check my epicenter hypothesis with random dates /times and check the results
I have just started doing that.
first random dates ( year 1600 to 2600) were taken and time ,as well as epicenter were seated from any of the actual major (8+) quake ( out of my previous 100 selected)
  The first hand results suggest around 45 to 50% follow the hypothesis.
Where as our results are up to 85%
  In fact 45%Accuracy is normal ...
This is because...we have..

15 degree margin on both side..ie 30 for each.
Now Zenith and Nadir for both Sun and Moon gives 30x4= 120 degree

Rising and Setting have 20x 2 =40 degree

120+40=160 degrees

So probably is 160/360=44%...

Thus up to 50% is just by chance
Anything we'll above it need to be noted
