Learn English – What’s a more formal way of saying “a bit of a stretch”

phrase-request

Say you've just read an online discussion post and want to comment on the fact that the writer has jumped from point A to point B without attempting to convince of the validity of the connection. What could you write on that would be more refined than "that's a bit of a stretch"? I should mention that I don't have continued interest in understanding their reasoning and am looking for no more than another way to say "that's a bit of a stretch."

Tell me if this fits your requirements:
