Think I addressed reply to the wrong party.
In any case, via simply looking at the numbers, the differrence (error) is about 1/10 NM. Doing a ratio and proportion, I get 528'.
Of course, 1' of arc is 1 NM at the equator, at 51.5 Degrees North (roughly), I believe it would be less, though off hand I don't know how much less. Does this help.
