I have been running around the Raijin controlled systems noticed that occasionally destroyed interceptors will drop 2 hearts. Only noticed this on free range ones that interdicted me in controlled systems. Rarely fight hyperdicting ones as they won't count and never really looked in a CZ.
Before the caustic cloud dissipates another interceptor will jump in and bee line it to the hearts and scoop one up.
Shooting this interceptor only drops one heart but another interceptor will jump in and scoop it up.
Rinse repeat with it dropping one heart as well.
Destroying the heart changes things a bit as an interceptor will jump in but it just wanders off without visiting the destroyed interceptor.
