The calculation for EIS compressed data volume onboard through MDP status curves is descirbed [here|CompressionFactorStudy].
The way to calculate EIS onboard compressed data volume with MDP status curves was descirbed in previous post abut EIS DC factor: [check it here|CompressionFactorStudy].

The following links show DC factor variation in different scenarioes (eg. AR, QS for SCI_OBJ, 1", 2", 40", and 266" for SLA). A conservative estimation of avgerage factor is indicated by orange dash-line on the plot, which could be used to improve EIS planning tools when the number will be approved/corss-checked.
