A question for those more experienced than I am:
Until this point when I've been sending two small cargo ships to one planet in a single "attack" as described in bashing, I've been sending them in waves. Other than taking up another fleet spot, are there any dangers / drawbacks to doing this that I'm not aware of?
My thinking is that since I'm just sending cargo ships to idle players it's not going to be an advantage to have more "firepower" of a second cargo ship.
I think I maximize the resources I get from the attack
If for some reason something went wrong and my first one got destroyed, would I be able to use recall to send the second cargo back so it doesn't get destroyed by defenses on the planet? (I haven't used recall before)
The main reason I'm using this is to ensure that I get the most possible resources from people. Am I correct in the situation below?
Say player X has a pretty good (for me) amount resources of various types last time I got a probe check from someone / sent my own probe (I don't have them yet)
Situation #1
I send two cargo ships in 1 wave then 20000 is the critical amount of resources
Player X has ------ Then I get
20000+------------ 10000
20000 or less ---- 10000 or less (half of what's there)
examples
18000 ------------ 9000
15000 ------------ 7500
12500 ------------ 6250
10000 ------------ 5000
7500 ------------- 3750
5000 ------------- 2500
2500 ------------- 1250
Situation #2
I send one cargo and then a second one at either a slower pace or just wait and send it at full speed too so that they both arrive at the planet withing a 30 minutes window then 15000 is the critical amount of resources
Player X has ------ Then I get
15000+------------ 10000
15000 or less ---- 10000 or less
examples
18000 ------------ 10000
15000 ------------ 10000
12500 ------------ 5000 + 3750 = 8750
10000 ------------ 5000 + 2500 = 7500
7500 ------------- 3750 + 1875 = 5625
5000 ------------- 2500 + 1250 = 3750
2500 ------------- 1250 + 625 = 1875
Summary: For this example, if the planet has 15k or less, the wave attack gets you 50% more resources. Between 15k and 20k there are gains too but it is less significant. Above 20k it doesn't matter.
So basically if you send two cargos to one planet in a wave vs two at once
If the planet has less than 20k at the time the first ship gets there, you'll end up with more raided if the second ship arrives on its own later.
I guess the danger here would be that in the time between waves, someone else could come and raid the planet to take half of what's left or they could suddenly become active again and have something waiting there for you (seems unlikely)
Am I forgetting anything else?
Also since the planet will be producing between that period of time between waves it's a trade off between the chance that something will happen to add defense / another player will raid vs you getting more resources depending on how much that player produced additionally in that half hour
So is it basically trading a fleet spot for the chance of a possible 50% greater haul?
(And then adjust the times between waves for comfort level between possibility of a raid by a different player vs getting up to half of whatever they produce additionally in the time span)

EDIT: All three coming back with 5000
And looking at the combat reports of course I thought about the ratio of different resources now.
Wave attacking will have the added effect of possibly increasing the amount of the resource the defender has the least of.
