K32 plot size differences


I have 2 different plotters. And using Madmax for plotting.
Plotters configuration near the same.
1 plotter creating plot with size - 106,3 GB
2-nd plotter creating plots with size 108.8 GB.
All is working. But perhaps somebodies know why plot size differents? This defference quite important for me.

I have araound 700 plots. None of them is 108.x even none is 107.x.
106.x is correct.
