Need for better benchmarking method

Words that I read: 1890

Words that I wrote: 145

It seems like my reading speed has increased since the number of words I read was over 1500 two days in a row. However, I am now sceptical about this benchmarking method of counting the number of words I read as a measure of my reading skill. This doesn't reflect how much I understood about the article, which is the most important thing about readin an academic paper. Sooner or later, I might switch the method to measuring the time it took to read a paper and caclulate the speed as word/second. Anyways, this habit is making me some improvement on having a habit on reading and writing something everyday. There are only 3 days of data about my reading ability and I can't conclude anything statistically meaninguful, so I will just keep on doing this as I currently do until I get enough data.
