Best I made it is -602, and that's WITH using all the downaccel windwalls on the left side all the way down. I have four hooks on the second ladder bit in the sky right before the really tall single pole. I didn't even use any hooks until after the third two platform bit in the sand section and had about 10 seconds left right at the end where I had to wait.
(I put a sticky note on my monitor indicating where the column of windwalls were because genuinely I missed it so many times I started crashing out)
