I think of it this way ->
1 keypress = 1 action
If you set up a key to spam /click at 3 times a second then that is more than 1 action per key press. You have just entered into a gray area. I would be very careful about macroing your keys to do multiple presses.
In general people here mash their keys meaning they press the key about every 200ms (5 times a second). Some claim to press keys at 8 time a second. I have trouble with going beyond 5 physically.
