That's not what made it sound like Yoda. It was sticking "has been" at the end, and I agree there was a better choice stylistically: "Crazy how effective this admin has been at making everything worse."
Didn’t even strike me as weird phrasing. Or rather: strike me as weird phrasing it did not.
"It's," perhaps?
Yeah, nope, you're right. Not sure why my brain thought "The". Haha. I blame on the roughlu 2½ hours of sleep I got last night. Yay insomnia!
