I can't explain your observations. On my machine, I tried cat`ting entropy_avail every .1s. My observation it that in consistently rises until it hits 190, when it instantly drops to around 140. The upper bound of 190 seems to be pretty consistent (very occasionally it drops earlier, it never seems to exceed 191), where the lower bound goes between 130 and 160. I'd assume this means that I'm low on entropy (especially because the post indicates that below 200 indicates that the system is running low), however I cannot think of anything special I am running that would be eating entropy. Also, mashing my keyboard and mouse does not seem to affect the rate of entropy accumulation. Decreasing my sample rate also does not seem to slow down the rate of accumulation, so it looks like cat`ing does not affect the value on my machine.
