I got married yesterday. If the trend continues tomorrow I will be doubling the number of wives I have every day. I expect to be married to the whole human race by the end of the month.
Your childs increase in reading speed by contrast is highly unimpressive.
Not to ruin the analogy, but wouldn't the number of wives you have just increase by one every day? Because 2 * 0 = 0?
We need more than two data points to get the relationship. It may be that monochr will have a fibonacci progression in the daily number of wives...
