Nice of you to post this samples but I'm still wondering how do they compare to a "no filter" shot.
Using a lens without a filter is something that I don't do so my comparison was based on whether the Hoya Pro1 achieved any noticable improvement over the non coated filter - I think it does BUT is it worth paying 3 times as much as flare is still apparent, abeit reduced.
You might like to visit this site with the following Finnish translation:
First shot is with good multicoated lens, in second there's uncoated El Cheapo in front of it, in third pic there's one layer coated El cheapo (with really bad optical quality, double reflection). Fourth pic is with high quality multilayer coated filter.
Next photo is ND filter with single coating layer in one side, after that there's uncoated CPl (but high quality one because reflection is symmetrical)
Last real condition shots have same "configuration" as in first four.
