I probably didn't explain it all right, but whatever i do seems to work most of the times. In late game, my AIP ends up being 500-600. With all datacenters, co-p's and possible superterminal I could bring it down to 300-400, but i don't always have to do that in order to win my game. I have one heavily defended world, where all the waves will come to. The rest of my worlds are very lightly defended but often have mk II, mk III grav turrets/tractor turrets + logistics to stall any enemies long enough for my fast fleet (or portions of it) to arrive. My fleet moves around, destroys threat, defends against CPA's and exo's and only makes actual progress when it's fairly quiet in my empire. Only ships with inconvenient immunities like raid starships can be a problem. A 100 planet game usually lasts about 20-25 hours. On normal caps endgame waves end up like 2k mk II,III missile frigs and stuff like that. I do have golems (medium) and spirecraft (hard) enabled at all times because i enjoy playing with them, but i don't need them to win my game.
with turrets i meant place them just in range of the wormhole, in the direction of your command center. The longer your turrets live the better of course, but you also don't want to give the enemies a chance to scatter in all directions (which they do) and possibly invade other less protected worlds. Several mks of HBC's, lightning, flak and possibly sniper/spider (sniper and spider as far away from wormhole as possible of course) and it takes down any regular waves (except teleporters, but that's why you build the cc at the other end of the turretball, still in range of the HBC's).
I guess it all depends on different playstyles... As i said before, higher AIP doesn't have to be a bad thing. Yes, destroying more warp gates costs more AIP, but personally I rather have higher AIP than more warp gates alive. It's a matter of preferences really, and to me it's all about being in control. AIP is something to be really careful about, but if you can handle it, go for it. I NEED a large amount of worlds in order for my playstyle to work properly. of course i don't pick them randomly, i carefully select them after doing intensive scouting.
Higher AIP means bigger waves, more enemy reinforces and all that jazz. But it also means more resources, more possible shiptypes (ARS, fabs), easier and faster acces to your systems, more asteroids if you play with Spirecraft, etc.
And nowadays we also have the hacking system. More AIP means more hacking possibilities, which has turned out to be a very useful tool.
I hardly ever unlock mk II logistics... they really do cost to much knowledge. Only thing I've found useful is warp jammers. Some well placed warp jammers can buy you enough time to win your game.
Now I don't know what 10/10 is like and it's a very strong possibility that my playstyle won't work at all on doom. But it works well on most 9/9 games and it certainly works on 7/7 even with 4 of the worst AI types. Making slight adjustments for each different AI type I fight against of course, but the basics of what i do are the same.
don't know if any of this makes sense. I'm not incredibly good at explaining things, but i try.
