Typing speed will vary with the typist's endurance power. Yet, it won't be a constant speed.

The hands will start feeling the fatigue after an hour or so. Typing in a speed contest is different. The duration is short. The only focus for a few minutes will be on speed. Confidence level and vigour will be high.

But typing a text matter is entirely different. I have seen days when I had worked round the clock for 24 hours. But that was with breaks. Yet I was tired and my hands ached. We are humans, not machines.

The last thirty minutes will break the back.
i think so
x/30 = 1800/40
