OK I'm just trying this out now and...
EDIT: Never mind, I just counted the grids manually (and wrecked my eyes in the process)
But now I have a recurring problem in that it still doesn't like symmetrical; I am inferring because there might be conflicts with the slider velocity. Any input on exact estimations (???) as to how much points should be away depending on the slider velocity? E.G. my 5 point symmetry for 1.28 velo would be different than that of 1.5 slider velo... Pic below uses 1.28 slider velo

Place all of your points symmetrically in the grid first of all.Admittedly I am finding this very difficult to do on Grid Level 3. Any advise?
