Flak 88 : One-Shot Kill? How Effective was it Really?

Flak 88

The Flak 88mm is often portrayed as a Wunderwaffe that could one shot kill most or even any tank in World War 2. The question is, does the claim of the one-shot kill hold up to data we have available or not? For this we look at data from Flak units, but for context also US Tank Destroyer Units, German Sturmgeschütz Units and Tiger Battalions as well.
