Elite: Dangerous PvE - Mobius

Does anybody have information or know where to find out about Ships and there Mass Lock score/value and which ships affect which ships.
Im lead to believe the Federal Dropship has a decent score in this and can just about lock out all ships, but further info would be appreciated for the whole fleet.
Dont mind if its a heavy tome i got to read

Many Thanks

I was under the impression that it's a function of relative mass. So you're either mass locked or disrupted by "heavier" ships, and you disrupt or mass lock "lighter" ships. It doesn't appear to be done on a score, as evidenced by the sudden loss of disruption or lock as you exit the mass influence, rather than a gradual breakout.
