Depends on shooting position, but the further back towards the mag well you mount it the more it is likely to be influenced by wobbles.
I used to mount 2 Spartan flush cups in my stocks, one as far forward as possible for use when prone or sitting on a steep face, and one back closer to the mag well for standing shots (bearing in mind that a standing shot unsupported should be kept to closer targets due to being less stable).
I almost never used the flush cup closest to the mag well other than for practice but happy to have it for that one time it may come in use.
If I set up another long range rifle I will do it the same.
You can still shoot standing off the front flush cup but you must support the rifle, where if you had a mid mounted flush cup you wouldn't need to support it.
I did see a guy on YouTube using a tripod with a set of shooting sticks to support the butt that looked to work very well but more crap to carry (something to bear in mind).
