Well...what I mean is it's harder to get a good time w/ this trick than Underground. The frequency of landing it good (at least for me) is less often. I have under 19.00 12 times now, but it took 1800+ tries to do it the 1st time & that was 18.84. It's just that it's finicky & you have to be precise. I think 16.xx may be possible, but I don't feel like putting my time there right now
