This is from one of the developers in a different thread.
Let's start by talking about tactics scoring.
Based on your feedback, we know people find it demoralizing to gain so little and lose so much, based upon getting Tactics puzzles right and wrong. Of course, the main culprit here is **TIME**. You earn less for your hard-won successes because you took “too long.”
To allow more reward for thinking carefully about the solutions to each puzzle, we have tweaked the scoring logic: Time is now less important, and the base amount you can gain (or lose!) from a given correct solution has been increased.
Hi guys!
I had reached 4100 rating in tactics a month back. That time, the points used to increase 1. 1. 1. 1. 1, Even on 100%
Now, after a month I opened tactics trainer with a rating of about 4080. Since then, every puzzle I solve, I am getting 4-7+ points, while before maximum to maximum i would get 2-3.
It's amazing, this change! Did something happen which I missed?
