Rolling Depth

In Basilisk, the only change I made from 3.2 to 3.3 was increasing the rolling depth by multiplying my bins by .99 rather than .95 every time a wave hits, and it gained me 2 ranking places!(From #8 up to #6). So, I was curious, what rolling depths do other people use in their guns? Also, are 1000 round battles good for testing rolling averages? I like 1000 rounds since it lowers the margin of error, but it might distort my results because it's long term learning, not fast 35 round learning. Thanks!
