How do I do a no-dip muscle-up? (read description)

I'm currently at around 76kg bodyweight right now, however, when I was at around 68kg, I was able to do 17 muscle-ups in one set (no chicken wings, no kipping, no nothing). However, I still wasn't able to do a no-dip muscle-up. It's actually starting to feel impossible at this point. There were people who were able to do WAY less muscle-ups than me, but could still do a no-dip muscle-up. The most I could do is pulling below my sternum, that's it. Is there any kind of technique I'm missing? I was looking for some techs on YouTube, however, all videos show 2 exact same techniques which didn't work for me. And yes, I am aware of the fact that endurance is mostly not connected to explosiveness, however, I still think that being able to do 17 muscle-ups but not a no-dip muscle is not normal.
