Ive gone though the beginner videos as well as early stage tournament play. In terms of live mtt tournys, are the strategies discussed in the videos applicable to live games as well, or better suited for online?

ive played a couple live tournys since joining and watching these videos, applying the strategies laid out within them. I've done noticeably better in the 10 I've played (improving from mid field exits to top 10's and top 15's), is this just dumb luck or are they really applicable?
