Vocabulary-Note-Down Velocity

I use a Burn-up chart to benchmark my performance of writing down and translation of English vocabularies.

This is the result. The x-axis represents time and the y-axis describes a number of vocabularies. It seems that I use approximately 80 seconds for each word. The red line illustrates velocity from every word.



Thanks to Aj. Jittat for the Burn-up chart idea and software.

I have to do it better next time. :)
