That's another thing I distinctively remember from English class in Germany, being taught the British pronunciation that, at that young age, was much less familiar to me than American pronunciation, and some slight confusion around that.

I’m a native (non-American) English speaker and the American pronunciation, to me, doesn’t sound like keht at all. (German was technically my first language, although English became my main language at an early age, so I’m quite used to German accents, so it’s definitely not caused by the native accents imho)

I once (when I was ~15 or so) had an argument with a kid who simply would not believe me that the letters C-A-T aren’t pronounced keht

It's also definitely not the case that the "a" in American English "cat" is pronounced like "a" usually is in German. In that case, the "a" sounds much closer to a German "e" then a German "a". The IPA for AE "cat" is kæt, not kat (where in some parts of Britain it actually is kat).

The soccer thing is pretty funny though. :)

I wouldn't write this, but I would absolutely say it, and it doesn't carry the rough affect of something like ain't.

Still, pretty minor thing to nitpick about.

I'm not sure if English is your first language, but this should be, "if you have interesting technical analysis..."

Everyone can pick apart the mistakes of others, find mine!
