When attacking a planet I used to try to time the pressing of the attack button with the odds being displayed. Sometimes it seemed like I could get good odds this way, othertimes, not so much.
Lately I've been closing my eyes and waiting for a moment before pressing the attack button. I haven't kept exhustive track of my results, but it seems I do a bit better using this more random method than I did when trying to time the attack.
Anyone have any ideas on the best way to optimize your attack odds?
