Coast for loading and safe release. Gen5 reserves 400 s of zero-force loading coast per payload for the declared 355 s cycle. Both architectures keep 5 s pre-release and 20 s post-release zero-force guards.

Command flexibility and installed cost. The ideal ground-pretrimmed spring closes both target families at the 1 N and 5 N gates. Preplanned targets give no established Gen5 propellant or initial wet-mass advantage.
