Groove is the thing that had me stuck and now I understand you need to raise up groove before you schedule an 8hr high popularity item. Groove is gained properly on 4hr high popularity efficiency items, the 1st row being useless because the 1st row generates no groove. Therefore for the 1st two days use 4hr items that are high popularity or highest possible. Once your groove gets to above 30 go ahead and schedule the high popularity 8 hr starting day 3 to 5 to finish out the week. To recap the 1st 2 days are groove raising days using 4 hr same category items that give efficiency. Day 3 to 5 when groove is at it's highest schedule an 8 hr high efficiency item and items that give it efficiency. I got the Chopper and you guys are going to like it.
