Adding edited for clarity and legibility:

Todo/Daily damage = Str * Crit * Delta

Habit Damage = Str / 2 * Crit * Delta / 2

Where "Delta" is the change to task value as you click it. Its formula is: 0.9747^Task Value and ranges from 0.45 in blue tasks to 1 in yellow tasks to 22 in red tasks.

For perspective, Str+Crit together grant around a 4-6x multiplier to your damage on average with high strength. This means your damage would range from 2-6 from blue / yellow tasks to 20-130 from red tasks, assuming negative task changes work this way and don't cap out at 1.
