YouTube is very serious about Copyright. They usually review DMCA notices in just few hours, no matter if it is holiday or weekend. They are required by law to do so. If it takes forever to issue a takedown, the problem is somewhere else, for example usage that may fall under fair use, derivative work etc.Push things faster usually.
EG - You send a strike but youtube is taking forever to review or you are having issues actually taking something down he can get it done far quicker.
