So I'm a bit curious as to whether or not pirate battles in later planets have a better chance of dropping green, blue, or purple crystals. Couldn't find anything on forums about this, so I'd like to start a thread where, players record what planet they've fought battles on, and what crystals have been rewarded. Here's what I got, so far:
Planet 3
Chapter 10:
19 battles fought
17 wins- 12 yellow x9, 6 green x8
2 losses- 4 yellow x1, 2 green x1
Chapter 11:
161 battles fought
158 wins- 12 yellow x73, 6 green x82, 1 blue x3
3 losses- 4 yellow x1, 2 green x2
Combined:
180 battles fought
175 wins- 12 yellow x82, 6 green x91, 1 blue x3
5 losses- 4 yellow x2, 2 green x3,
Planet 4:
Chapter 10:
384 battles fought
314 wins- 14 yellow x158, 7 green x147, 1 blue x5, 1 purple x4
70 losses- 6 yellow x31, 3 green x39
Planet 5
Chapter 10:
300 battles fought
250 wins- 17 yellow x127, 9 green x118, 1 blue x1, 1 purple x4
50 losses- 8 yellow x21, 4 green x29
Chapter 12:
131 battles fought
118 wins- 17 yellow x53, 9 green x60, 1 blue x2, 1 purple x3
13 losses- 8 yellow x5, 4 green x8
Combined:
431 battles fought
368 wins- 17 yellow x180, 9 green x178, 1 blue x3, 1 purple x7
63 losses- 8 yellow x26, 4 green x37
As of 4-22-2014
Still, prolly a ways from statistical significance, so far, but here's the number's crunched:
Planet 3:

win: 12 yellow-52.94%, 6 green- 47.06%
loss: 4 yellow- 50.00%, 2 green 50.00%
Chapter 11-
win- 12 yellow- 46.20%, 6 green- 51.90%, 1 blue- 1.90%
loss- 4 yellow- 33.33%, 2 green 66.67%
Combined-
win: 12 yellow- 46.86%, 6 green- 51.12%, 1 blue- 1.71%
loss: 4 yellow- 40.00%, 2 green 60.00%
Planet 4:
Chapter 10-

Planet 5:
Chapter 10-

lose: 8 yellow- 38.46%, 4 green- 61.54%
Combined-
win: 17 yellow-48.91%, 9 green- 48.37%, 1 blue- 0.82%, 1 purple- 1.90%
lose: 8 yellow- 41.27%, 4 green- 58.73%
Instead of posting to update stats, gonna edit. I think this will allow this thread to drop down forum, as it won't receive new posts. If anyone else would like to post, editing instead of re-posting is probably a good idea. Please make sure to date each edit.
At this point, my numbers seem to show that the drop rate for blue crystals does go down slightly from 3rd planet (although I don't have nearly enough numbers from the third planet for my figures to be statistically significant) to 4th planet, and again from 4th planet to 5th (not including the higher drop rate from chap 12). Of course, with such a low drop rate in general, this could easily be attributed to chance.
Also, it seems as if the higher value crystals (green, blue, and purple) do have a slightly lower drop rate when you're in an earlier chapter, although a full analysis of that factor won't be possible without a lot more data. So if anyone does decide to start adding their own stats to this thread, please also include which chapter you're currently in as that might make a difference.
