[Resolved] GC4EQAQ cache-to-cache distance 238,900 mi

I have a challenge from before the new guidelines that never had a checker...GC4EQAQ. It is just like the checker for our GC3C3HK but a larger distance of 238,900 miles. It was published with the current convoluted verification (see cache page) because challenge checkers weren't around then. I'd love to simplify it for people. Thanks so much!

It looks like at least nine of the last ten finders have used the distances from home method, since only one of ten qualifies using the cache-to-cache distance.

Thank you so much for the quick response!
