do you guys think a 15.780 is possible in L1?

Don't think so. After a hundred or so attempts I've only achieved a 15.790

I tried a lot too, but it doesn't seems possible.
If it was possible you would have to hit the perfect spot on the trophy, somewhere next to the handle

Yeah I think so too, you have to spend a lot of time and tries to get that sub .790

you know what I'll give it a try now

Good luck, : )
But I still think it isn't possible

This aged well

It's possible, I managed to get a result of 16.18. I somehow reset 2 milliseconds without an bug, so you can also do it with an bug. (Sorry for possible mistakes, I don't know English very well)
