The linear variance increased at about 214 m2 day1, which corresponds to a standard deviation of 207 m gen112 over a 20 day life span. Statistical uncertainty in this estimate can be expressed using a distribution-free maximum likelihood method, which gives support limits of 186—270 m gen112. However, the main errors come from extrapolating from this experiment to the dine as a whole.
