Slide 8 is empty of dot map, I delete it since the data is totally broken
So the range of usable data would be started from like slide 1~4, and slide 9
I can not yet get anything obvious from the dot map.
I am thinking to add up the dots by my human eyes. Yes, and then calculate the dots manually then input the result into google spreadsheet. That's the best procedure I can do now.
The only way that makes analysis possible.
