That's a good question.
Let me tell you how tactics train you the way I see it.
The tactics are very repetitive. You can see the same position up to 3 times a day, but never the exact same position. This teaches you to memorize positions and what to do in them. But the weird part is that we don't notice these positions when we move back to the game. Instead we go by bad habits.
I believe that puzzles in chess being done repeatedly over a short period will not effect your play immediately. However, it will improve your play about a month in the future, if you take it easy on chess altogether.
That gives our slow brains to remember and be able to discover how to get to certain positions and what to do with them.
I am not playing much now because of this experiment but when October comes I am going to anchor down on slower games that I am not used to. I am hoping for good results, but it's only an experiment.
If you have unlimited access to puzzles you will increase much faster. I already reached 2400 since 2300.
Interesting. I have the gold membership which allows 25 puzzles per day and think it is more than plenty.
After about a dozen, my concentration dips dramatically and feel like it is a grind to complete the 25.
Like other have mentioned, the 2300 is giving the me the most challenge at the the moment. I am scoring a respectable 60% accuracy rate but now they take like 2-5 minutes to figure out where as under 2000 puzzles I can do under less than a minute.
It took me a while to make 2200-2300. But then when I reached 2300 I reached 2400 like the next day I think.
Since then I have made my peak to 3076 I believe. I am stuck 3001 area now.
Thanks for the quick response.
Did you find that the puzzles training translate into your games?
I only ask because tactics is the weakest area of my game. It cracks me up doing a game analysis and missing a simple tactic vs consolidating a winning position that albeit is a win but tactics scores style points.
