I think the difference that occurs is acceptable because the difference that occurs may be a cause, as follows:
1. the machine Rewind time slot (The same as always) have included the time of the Dip 2 Dip 3 Rewind, but the channel [In detail], save time by the machine Rewind.
2. the channel (The same as always), there may be a time to meet with each of the address.
3. the channel (The same as always) time to mix the liquid will have a working time of the employees do not comply with the reality. But the channel [In detail] is the actual working time of employees.
