multi game series umpire rotation

[bniu]

I've got a best of 7, best of 5, and a best of 3 series to assign to a 6 man crew. What is the alignment supposed to be?

For example, in the best of 3 series, for game 1, where do I have the umpires start out? My umps are in order of seniority: Crew Chief, Associate Crew Chief, Assistant Crew Chief, Umpire 4, Umpire 5, Umpire 6. I am doing standard rotation: HP->RF->LF->3B->2B->1B

In addition, for a single game playoff, is it better for the crew chief to have the plate or be at 1st base? Some ppl say that the crew chief outta be at 1B and have the 2nd most senior guy behind the plate...
