Hmmm. From my travels through Latin America, I would rate Colombian accents as by far the easiest to understand. Without exception, everyone spoke with clear diction and enunciation. I would definitely not rate it "very hard" - that would be reserved for the Honduran accent, which I found incomprehensible even spoken s-l-o-w-l-y.
Looks like they're rating "difficulty" as "difference from Spanish in Spain". Considering that Spaniards only represent about 10% of the total Spanish-speaking population, I'm not sure that's fair.
