In smallbore prone, that change is typically a couple of 1/4 moa clicks which can be quite noticeable over a 10 or 20 shot card.
More common applications in NZ are hunting and multiposition "precision rifle shooting", where attaining a good stable neutral position tailored to the shot is more important and sub moa variation can be absorbed.
Even in F Class and Fullbore target rifle, variations in the slope and shape of the mound might render minor adjustments to the LOP on the day beneficial. Someone who shoots those disciplines might be able to comment if that is true.
