Harvesting math

[Arusha]

Hi all,
Can you pls tell me how it works?
If I get a planet with 750CO means it produces that amount per hour. Fine.
The small harvester has a cargo of 250, in 3 sessions it will finish the hourly capacity.
But, how long does it take for a harvester to load 250?

Lee said each trip, 30 seconds is spent loading/unloading. It wasn't clear whether he meant 30s total per trip (15s each), or 30s each for loading and unloading.

Other pertinent information is that ore production values are per hour but ore is produced every 5 minutes, and harvesters will wait at a planet of no ore is present but will leave as soon as there is something to transport, not waiting to fill.
