Stuka was credible because it have better intelligence/targeting, contact with ground observers.The Battle is about the only RAF asset that might be considered a CAS asset...and we can see how successful they were. Conversely, the Stuka was a credible
It had escorts, not a fighter sweep that went through area in the same time frame (minutes different than the Battles) and the formations never saw each other.
Not sure what protection the Stuka, had, if any in 1940. we know that the Battle didn't have any (or very little) and using a 16,000ft engine in a CAS airplane with a two pitch propeller was not helping anything.
You could have magically replaced every Battle with Ju-87s (pixie dust) and the results would have hardly changed.
