Saturday 12:30

I think that's a personal best for Saturday, at least without outside assistance, and compare the times for Thursday-Friday. I couldn't really tell if this was a hard puzzle or not but 1-Across was a nice long gimme ("Woman who spends money on a younger lover, in modern slang" SUGARMAMA. (Is there old-timey slang for this? "Sugar Daddy" wouldn't be considered modern, would it?)). Saturday usually has fewer straightforward things, but there was nothing too terribly misdirecting, which I would rather see, even if it takes longer. Clever clues for regular words make me smile, Will Shortz has said the best puzzles could be Monday OR Saturday, differing only in clues. But clearly, that's not actually a standard they use. Friday-Saturday are always lower word count (remember, lower word count means longer answers and more white space, so harder) than earlier days.
