Sharps drop rate

I've found them harder to come by recently but I do still believe its simply luck. Averaged about 10 Luke shards a day from roughly 30 attempts per day which is reasonable. Rarely go higher than about 12 but have found myself getting 2 or 3 some days. Got 3 total yesterday but already had 8 so far today.

I'd take a guess it is 33% drop rate but that doesn't mean you have to get 1 in 3, however nice that would be.
