You will get as many different answers as there are ways we learn to shoot coming up.
Old school shooters like me will generally just hold the wind or hold both wind and elevation.
If you run the numbers I think you'll find that with the adjustment you made, IF the turrets had been zeroed you would probably have still shot over.
With that much angle you just have to go ahead and do the math or just have an ACOS and level on your rifle like the one's that Len sells in the LRH store unless you're really good at doing math in your head.
You can just multiply your range at 30deg incline/decline times .90 and get really close, or you can do the reverse. You had 587 for your range so it's really easy to just subtract 60 from it and end up with a range adjusted to 527 or dial up 525 if you have ranged turrets.
If you get steeper than 30 deg you really need to work it out as accurately as possible.
We used to shoot coyotes off of the caprock on a friend's ranch and a lot of those shots were well over 45deg, some as much as 80 deg down angle and and the drop was 500-900' straight down in places. Shooting upslope was even more of a challenge since you had no clue what the wind would be doing on top. We had the same kinds of challenges shooting off of the Mesas up near Tucumcari.
