That's why it's approximate. Gosh.
An approximation is a "a value or quantity that is nearly but not exactly correct." It's more likely than not that at least a handful of the OP's approximations are not even "nearly" correct, since their calculations do not include some of the largest factors in determining the actual weekly running costs (source material royalties, author percentage shares of gross box office receipts, any contingency fund monies spent, non-budgeted sundry or maintenance or upkeep, etc.). It's impressive... That's for sure. But I don't want people to get the wrong impression here on what it costs to run a show every week. When considering all of the add-on expenses the OP isn't even accounting for, it's damn expensive. No matter the actual size or cost of the production. Someone comparing and analyzing publicly available data cannot make an accurate determination of actual running expenses because many of the largest deciding factors are confidential (i.e. contractual obligations between the producers & authors, or the star, or the rights holder, etc.)
