Puzzle streaks are wrong IMHO

They count the number of your streaks not the number of solved puzzles. Which leads (at least me) to happily (but not deliberately) to throw away my current streak. So motivation wise it seems like this is not ideal situation. Maybe people could suggest something, like to count both or not count at all (only the highest streak for example). I don’t know. This is just my experience.

You are simply implying that you are unmotivated by the streak.
If you don't have fun playing with puzzle streak, then don't play it. Puzzles, puzzle storm, and puzzle racer still exist.
