I spread it, leaving a space between each series, and I double the whole thing.
I fill the grid with all the series, one column for each team.
When it is all filled, we can see that there are series that are played consecutively. I will shift lanes to separate these series. When I do the shifts, I do them in the Black Box first before doing them in the grid under. It is very important to do the shifts in the Black Box because that is what will be used for the Layout of the schedule.
Here’s the grid after shifting lanes. Note the number 1 to 52 in the middle, that are not in order anymore, representing how I shifted lanes.
Here’s the Black Box as well. Again, note the number 1 to 52 in the middle, that are not in order anymore, representing how I shifted lanes.
