Well since it's got to the extreme level of even organofcorti commenting on it, I'll post the magic numbers for citronick
All history:
23.51741743 BDR :
26 Blocks - good!
Since the halving (i.e. a subset of the above numbers):
11.32364258 BDR :
11 Blocks - no problem at all
i.e. he's found more blocks than expected, and since the halving, very close to expected.
I've not really said anything about it since my post on the Bitmain S9 stats, since as I said there:
Kano it would be interesting to know if s9's are in some way having a negative effect on your pool. If they are it would be in the best interest of the pool that they go somewhere else including mine. Just curious.
Well for miner types directly connected to the pool (not via a proxy)
Since they first existed:
67.76844935 BDR for
60 blocks - so not excellent, but not impossible: CDF[Erl]
0.842606Since the halving (excluding the data before the halving):
63.99816529 BDR for
57 blocks CDF[Erl]
0.825166 (thus a little better)
But since the halving there are worse - the longer term figures are (usually) statistically more relevant
(there seems to be a v2 bmminer that's found no blocks so far, but the BDR is only
0.07520162)
They do have the worst luck and the worst CDF on the pool for miner types connected directly to the pool.
But the numbers aren't in the realms of improbability - and it doesn't include any using proxies.
However there is (only) one "proxy type" with a worse CDF
stratehm-stratum-proxy-0.8.0
7.76724928 BDR 3 blocks: CDF[Erl]
0.983517As I said above, that's only S9's connected directly to the pool, if they use a proxy then they wont show up in those numbers.

i.e. the number in that quote
... so not excellent, but not impossible: CDF[Erl] 0.842606
Edit: actually the updated numbers since that post - since there's been a few more bmminer blocks and of course a higher BDR
bmminer
71.24030662 BDR :
65 Blocks CDF[Erl]:
0.785699bmminer2
0.19718556 BDR no blocks yet
