A recent BBC article reads in part,
Yellowstone officials say bison can run up to 30mph (50km/h) and are the animal responsible for the most amount of injuries within the park.
The phrase “the most amount of injuries” is like nails on a chalkboard to me. “Injury” is a count noun, so I feel it should be, “the greatest number of injuries.” Several grammar web sites agree.
Is there any national or regional variation that would make the BBC's sentence grammatical? (I am asking about prescription, not description. Is this an acceptable sentence in any standard variety of English?)
