Well, I wouldn’t support that tbh.
Yes, usually, only a few of your drones need to travel far, but on large spod rocks, you lose quite a considerable ammount of Ore over an hour. I wanted to do a bit of stopclocking for some rocks to have more solid data, but didn’t get to that yet.
Since Spod is the most available ore in nullsec (and also the second most expensive on paper), you will mine it for a long time. Hence, the impact is not as marginal as one might think.
I typically place my rorqs as close as possible without losing too much time with positioning. Usually within 500 meters (approch the rock, get bumped then wait until you are at 5-6 m/s and stop).
Just a quick example:
2 of your drones are 10k out => they travel at about 450 m/s with 4 NavComps.
takes them 22 seconds to unload the ore. Out of the 300 seconds you mine a minute with 5 drones, it’s 44. That’s 14%. or about 100k m3 in an hour. That’s only for 2 drones being out that far while all other 3’s are in perfect position (so, it’s an unrealisticly good approach).
