we're talking about 360s here, of course a normal horse can do a full gallop but certainly it cant reach max speed in so few time as mount and blade and cannot stop instantly no matter how hard you look on the internet for the whatever race you wish, also gallop speed is different horse from horse.
You're trying to prove that NW cav is underpowered in handling compared to normal irl horses by showing me races of famous horses, i can not help but to laugh about it, stop trying to turn it around.
they were trained to stand gunfire but certainly not in race or circus numbers, i work with horses in my summer holidays and i see them nearly everyday.
I don't know with what kind of trucks you work with in your summer holidays but I am mainly talking about the light horses which are comparable to the sport horses & average ponies. Not every nation used heavy and robust horses.
Check the turns, check the speed, check the right into canter. Those are kids on ponies. I bet they make their living on their famous horses.
