A Reasonable-CPU-Opponent should never react faster than 0.3s and they should rarely, if ever, react slower than 1.2s.
350ms (Elite) - 1,000ms (Casual) Range would be the most encompassing.
The decimal seems to be in the incorrect location on this game.
For example, the game’s reported 0.04 time should actually be 0.4.
A tie counts as a win for the CPU and the CPU just clicked a crab in 270ms - which is absurd for Complex-Reactions.
The CPU just 0-5’d me during a match where I had an average in-game response of “0.036.” and a Peak of “0.028”
