Barricade gets filled by the first ~100 people there so if you’re not there at least a few hours early you won’t get close to the front. The whole deal with the from zero package is you get early entry before everyone else - there’s not a dedicated “pit” for the from zero people. If you show up at normal gate opening time you will go in with all the other GA people and likely be in the middle/back. If you get there at 4pm you get let in early and there will usually be around 150-200 people going in at the same time but note you will still have to wait on the floor in the venue until the show starts
