Just FTR - 1 character per second is glacially slow - it's 12 wpm - fine for (slow) transcription, but the monkey typing exercise doesn't require them to know what they are typing out
Considering it's random characters being typed, and a skilled typist who is aiming to accurately type words out can hit between 70 and 100 words per minute - I would say that my monkeys could "type" an order of magnitude faster than 1 char per second
