Star rating is a poor metric, and one that does not accurately respect the actually difficulty spread applied in that map. Advanced itself contains many 1/2s, but is underweighted due to the usage of sliders and lack of spacing variance. Hard has minor variance in spacing and slightly more 1/2 clicks in a row. In fact, Hard specifically had the more strenuous strings of 1/2 circles changed to include sliders at detriment to the rhythmic consistency specifically to make it easier to play (A technique that does not, in fact, lower star rating much, if at all).
Plus, Logic's diff is literally 0.01 away from having the Hard icon. What's the problem with that? Don't degrade yourself by only looking at the icons shown and just assuming they're perfect representations of the difficulty spread.
Try looking at the map as well. That's a good start.
I "brushed off" the comment as Stjpa had already summarized my feelings, and the feelings of any rational mapper or modder, on the matter, in the post before mine - Advanced has plenty of 1/2 already, Hard isn't that much of a logical step up, but star rating is catapulted forward simply due to the spacing variances used.
It's also considered good form to post your concerns in the beatmap thread so they can be addressed there without appearing to be uncalled for, since you didn't do so I'm replying here.
