For general whitetail advice, probably
But elk, well I'm certainly rethinking that. They can, will, and do go uphill.
It also seems if the shot is less than ideal but still fatal, a straight line exit from the scene of the shot is often followed by a buttonhook, in any direction they feel like.
Elknut mentioned he's seen them go back to where they'd been before the shot. That resonates with me and I'll keep that in mind for the future.
About 15 years ago, I made a bad one lung, liver and gut shot with muzzy fixed 3 blade on a decent whitetail buck at the creek 600 yards behind my house.
Rascal ran down the creek then out of sight into thick 5 yr old cutover.
Found him 575 yards uphill in center of my backyard. He had ran a half circle. Guts had plugged exit hole and I'd lost blood. Almost tripped over him in the dark as I went home to get fresh flashlight batteries. I've never had another deer run that far using the old school muzzy heads. Worked out well, as I didn't have to drag him.
