In my experience, there are more significant digits when the data is exported/saved (to a .csv, for example) than what is shown in the ASCII plots. It seems like LSPP may round the data to declutter the plots.
My elout data in my most recent simulations reads ' 5.1223385526e-05', while the ASCII data in LS-PrePost shows only 6 digits, like you indicated. I hope this helps!
