Practice (in particular, learning where the crests for your door of choice are) is huge.
Also, if you just want ingredients, don't clear the giant camp (unless it has a teleporter spot and a purple patch), and do use a security crest. The star objectives don't affect your ingredient return, beyond getting nothing if you fail to complete the first star.
In particular, once you're confident that you'll be able to get one big progenitor before time expires, get the purple patches along the way / slightly out of the way before getting the progenitor, since the later you leave it, the more that will have exploded.
I'd be surprised if it was just level 16 that was anomalous in return rate, but can't even be sure I've tried 16. I'd check 15 and 17 since they're only 10% penalty/gains and should be of very similar difficulty.
