Yes, it looks much better:

debug.total: 10013 -> 0
debug.total: 10013 -> 0
debug.total: 10012 -> 0
debug.total: 10012 -> 0
debug.total: 10012 -> 0
debug.total: 10013 -> 0
debug.total: 10012 -> 1
debug.total: 10013 -> 0
debug.total: 10013 -> 0
debug.total: 10013 -> 0
debug.total: 10012 -> 0
debug.total: 10013 -> 0
debug.total: 10013 -> 0
