:up: Just 'per' is confusing, ornate, and archaic. It's Latin, and was used in expressions such as 'per yours of the 15th ult.' ('Yours' was a conventional abbreviation for 'your missive'; ult. was an abbreviation for ultimo, itself a conventional abbreviation for ultimo mensi - 'last month'.)
This sort of abbreviation did little to aid or advance communication, so people srted translating: 'as per your...'. This made 'as per' accepted in some circles, and people thought it would make them sound clever if they said thing like 'as per usual' instead of 'as usual'.
Avoid 'per' in this sort of context, unless you have the misfortune to belong to a business community that still insists on it. ;-)
