Very dangerous overtake!!!

So my current bike is Kawasaki ZX-6R 2019. This was the first trackday of the year and first trackday ever with this bike. Had many problems all day long... I was riding it like my previous R1 so my throttle control was horrible. Too early on the brakes, corner speeds zero, lack of acceleration so about 10s slower lap times than R1...
The bike is completely stock, no mods!
Those double right handers I did was little bit of the riding line when I came out that first right hander but still I think that overtaking was stupid move.
