My boss once gave me a sheet where he had used
=SUM(D4:D17)/COUNT(D4:D17)
quite a few times.
I wouldn't call that one pointless....
It does in fact serve a purpose, it gives you the average...
It's overcomplicated and could be done with a simpler formula, but it's not pointless...
I would say we need a clearer definition of the word "Pointless"
I (and I beleive Lewiy as well) was considering the definition : Does Nothing, Serves no purpose
You seem to include "can be done different/better/easier" in the definition...
By that definition I would say Vlookup is pointless.
