If it makes you feel any better (possibly not though) I was at approx 1000 hours before my first dropped and then I ended up with two on the same day... Go figure!
Only 300 my cousin was at 820 when he got his first but my other cousin was at 108 and has gotten 3 two of them in a span of 10 minutes dumb if u ask me btw I have 2 not sure when I got mine
