How long should we spend on each tactics puzzle?

I'm really struggling with tactics. I'm sitting around 2500 tactics rating and the puzzles are so tough that I'll often spend 20+ mins on a single puzzle, only to take an educated guess and get the answer wrong. Today I even spent 38 mins on a single puzzle!

Is it bad for me to spend so long on a single puzzle? What's the ideal amount of time to spend on each puzzle?

Whatever it takes. If you can solve it in 38 minutes, you probably had to have reached a level of understanding that will hopefully come in handy over the board some day.

The target time suggested, 44 seconds, is a joke.

I'm 1475 puzzle and typically take 3 to 8 minutes. I normally guess after 20 minutes. I hardly ever make the target time.

So 5 months later and I'm sitting around 2900 tactics rating now.

I'm still finding myself spending 20+ minutes on some puzzles and getting them wrong. Is it counterproductive to spend this long on a single puzzle?

My puzzle rush scores aren't great (32 in 5 mins is my record after hundreds of attempts), so I'm wondering if it's worth giving up on accuracy to instead practice blitzing them out faster?

Learning curve. Study the solutions, see if you can see the motif.

Real games are always too rushed. Even in 10 minute rapid games, there's only so much you can calculate. You end up just playing by intuition and making the same mediocre moves, game after game.

But puzzles give you a chance to play brilliant moves. They give you a chance to calculate epic combinations that you wouldn't otherwise calculate. And it always feels satisfying when you find that beautiful combination to force a win after going through every possibility.

Well, I'm kind of late here, but my lichess puzzle rating is around 2100-2200 ish, and I usually take about 5 to 10 minutes on each one. I find that when I get lazy and try to blitz through them, I only get about 1/2 of them right, but when I actually try and focus I normally get them right. It's kind of annoying sometimes when I get the first move or two right, but then play an inaccurate next move and still lose as much rating as I would if I had made the wrong move the first go. 

I think puzzles do help a lot in your chess understanding as they could appear in your games (normally in longer time control though, blitz is just intuition and forcing lines). Like I sometimes see new tactical possibilities after doing them. I'm pretty sure in a chess 24 Q&A session Karjakin said that you shouldn't spend more than 15 minutes on a problem or else you won't get that much time in IRL games. 

FYI- This isn't my account, it's my brother's account, and I don't do tactics on chess.com because it costs money. 

Go and check OP profile. He already passed 3000+ and you are not.

Paste your teaching methods on your wall yourself and try to get 3000+ yourself.

The same time as you spend on a move when you play.

Thanks, that was a good read!
