I think you are exaggerating a little. I can cut beans all day long with a 35' platform set on 34.5' swath and never ever nudge anything half mile rows and longer.Same with any tillage tool or planter.

The typical implement has way more side draft,or drift than any error you will see from a good dual frequency receiver.

I am not bashing RTK,just pointing out most operations have limiting factors that make RTK no more accurate than the lower priced systems which are way more convenient to operate for many locations.
