[ Units / Time ]

If I need to read a large volume of text for a project, I can either track pages read (units), or, do I track time spent?

So, I could set a goal of reading, say, 30 pages a day (measuring units). Or, the goal could be reading for 30minutes a day (measuring time).

Measuring by time doesn’t measure output.  In other words, to fully comprehend the content, 30 minutes of reading might only be 10 pages read. A goal of 30 pages might take me 3 hours.

I don’t have an answer.  I have to get back to my reading.
