You can "tune" a warp to point at the same spot every time, and get pretty consistent results.
But if you're serious about your game, you shouldn't put up with anything other than a tiny, barely noticeable warp.
Plenty of shots come up where tip placement needs to be exact. Why tear your hair out trying to guess
how to play around with the cue to get the tip where you want?
For me personally, I would go batshit even from a half tip of warp.
I guess it would be different if I had a really nice cue with a shaft I really love,
but I just look at the cue as a tool. If I can't cut my steak cuz the knife is bent, I grab another knife.
