After the first grid which is correct, the rest is not. Every other grid after the first, you count by tens. So...second grid 25, third 35 e.t.c.
So only the first grid is divided into 3 equal parts... 5-yds, 10-yds, &, 15-yds?
After that each grid is only divided by two... 5-yds & 10-yds?
That's where the confusion is. A video I watched said all the grids were linear.
15 - 30 - 45 - 60
That's what had me thinking, because nothing else in the game is linear.
Thank you sir,
Edit: Correction...The first grid is not divisible by 3. Half the grid is 10-yds and the other half is 5-yds.
