Ok. So I have spent about 30min looking through all CCP Devblogs regarding moon mining jackpots. I only found mention of it in this article:
This does not specifically mention whether there is any way to increase Jackpot chances. Does anyone know if CCP has specified elsewhere or in Dev Blog videos whether it matters if you let the extraction be automatically blasted by the moon drill, or does manual activation before the 3 hours are up result in a higher likelihood of producing a jackpot.
This is a purely logistical question to determine whether we should have dedicated members manually popping moons on a regular basis, to ensure we get the highest chance of a jackpot. Manual popping = more work = would be a logical reason to assume jackpot chance increases, but I was not able to confirm this myself from official CCP blogs or any other forum posts.
