Surprisingly hard to find this information - at least for me and a friend. We’ve pulled up zkillboard, however you get different numbers for the insurance payouts at the bottom. Pull one kill up and it says platinum insurance payout was 1.2 bil ISK, pull another one up and it is less than a bil, etc.
Generic googling on this produces nothing. There really should be some website that has a lot of popular ships and their payouts (maybe there is one and I don’t know?).
Another, kind of unrelated question. I don’t know about jump drive mechanics. Can you jump to a cyno (in capship) and then safe logout directly, or is there some timer or cooldown?
Insurance payouts are modified by CCP regularly to reflect market prices. It stops people being able to profit from it if the actual value of said ship drops significantly.
The kill you linked is from 2016, so this is probably what has happened.
