First time on a course

[KotOD]

When you play for the first time on a new course, how many shots do you "give yourself" at the end of a round? I'm not talking about reducing your score, but how many extra shots, on average, do you think that you take because it's your first time through? The reasons may vary, from blind tee shots and approaches, incorrect yardage markers (grrr) to first time putting on the greens, whatever.
