Got 500 Glav hunts in, 8 and 9 stars only to keep track of some stats

Note that this is only a limited sample size, so hopefully others who kept track will be able to contribute too

No R6 drops were doubled

In first 500 hunts, the R6s I've got were from: 
- 13 natural drops, so 2.6% personal drop rate
- 8 tail sever drops (from 494 tail severs), ~1.62% drop rate
- 3 group hunt drops (untracked, so % unknown. 2 from Dlinks, 1 from a group hunt with a clan member) 
- 1 Quest/Pity handout

The 13 natural drops were from hunts, tracked using screenshots: 
- 21, 85, 118, 268, 296, 301, 312, 354, 373, 398, 446, 474, 497 (and 535, 537 for the ones beyond the initial 500 so far, increasing the drop rate average to ~2.79% where I'm at)

While just a small sample size, I'd like to think that the drop rate for the Glavenus R6 should be in the ballpark of 2.5% for the 8* hunts, rounding down due to having hunted a handful of 9*s in there, with the tail sever being around 2/3rds of that at around ~1.67%
