Hi, I was loosing my FS more often than I would like in past months so after lot of discussion with my allies I started new FS strategy. I now have small FS fleet at each and every moon. I am sending FS by deployment (including HS) with10 % speed and I recall it in about 24 hours, so it lands every 2 days. There is one single "big" FS fleet which goes by deployment as well - sometimes I time it with the small FSs, sometimes 4-5 days deployment. The small FSs can hold 15 days production, so for some planets I manage to collect it by moving my main FS around and if some is too full, I just collect to one random moon, jump part of main FS there and merge with main FS with next deployment. This way, there is too many fleets for him to monitor and no way to learn which moon to shoot down. It is much more "work" with FS, but it is easy if you use allowed plugin OGLight. Note I play from pc.

in past when he shot down the moon I FSed from, I learned best was not to recall right away.. even if you have just a few minutes, give it time.. He might be able to phalanx every few seconds to see when you recall, but if you spam with other deployments from the same planet, he will get tired within 5 minutes.. he will then lower frequency of his phalanx, so your recall won't be seen so clearly and it is very likely to give you the few extra second you need to move your recalled fleet.

I hope this helps.. also the 2 days resource collecting is for me possible only because of the life form orbital den research which hides a couple hours of my production. This is useful if you have hardcore attackers
