A worthy challenge:
Code:

Sure, but about as hard as they get. I counted four applications of "advanced" logic, but by doing that analysis I slow myself down.
 
Took me longer than normal. Nearly got stuck half way through. Not sure what you mean by advanced logic. If it is of the form “if I put an X there that’ll mean three 0 in a row, therefore it’s a 0”, I can only remember doing that twice. Difficult, but not that difficult.
 
Another, apparently as hard as they come (and, with typical perverseness, only rated 2 stars when easy ones get 3):

I’m a bit out of condition with these, usually only doing the Saturday one. I did find this the hardest one I’ve done in a while. Worth more than three stars. Two, they’re taking the p.
 
It's the three star which take the pee (Saturday is always one of those!). I really don't get it – as I said above, the star system is perverse.
 
Just for the record (for the bystanders): the stars are "difficulty rating" not "easiness rating"!
 
I timed myself on today's "3 star": 21" (this isn't a race, it's a comment on the star rating system).

That was very easy. (39”, but who’s counting). Hard to compare with ones you've transcribed as I have to write them out first - and maybe working them out as I do so. Today’s was from the paper itself. The difficulty rating is just made up!

Really? So far as I can see, solution relies on getting the bottom left corner, which itself relies on getting the bottom right corner. 3 star in my book (2 star being one inference, 1 star requiring no inference at all).
 
Seems unworthy of 3 to me.
B2, C3, D3 are trivial, F6 leads to A6 and then fill the rest in.

Your logic agrees with mine; our rating just differs on where to set the threshold (one or two inferences). I don't recall seeing a Kurosu which requires more than three inferences, so making this one 2-star offers very little step up to 3-star (unlike the Mail's "difficulty" rating, which seems to assign 3 stars when the grid can be solved by inspection with no inferences at all).
