Anyone have any info on how many GHS-THS it takes to find and solve a block?

I am thinking of starting a private pool and only allowing x amount of members totalling x amount of hashing

At present difficulty [34,661,425,924], finding a block is represented depending on hashing power. I did a few "What If's" based on assumed hashing power:

50 TH/s = 34 days, 11 hours (can vary greatly depending on your luck)

60 TH/s = 28 days, 17 hours (can vary greatly depending on your luck)

70 TH/s = 24 days, 14 hours (can vary greatly depending on your luck)

80 TH/s = 21 days, 12 hours (can vary greatly depending on your luck)

90 TH/s = 19 days, 3 hours (can vary greatly depending on your luck)

100 TH/s = 17 days, 5 hours (can vary greatly depending on your luck)

110 TH/s = 15 days, 15 hours (can vary greatly depending on your luck)

120 TH/s = 14 days, 8 hours (can vary greatly depending on your luck)

130 TH/s = 13 days, 6 hours (can vary greatly depending on your luck)

140 TH/s = 12 days, 7 hours (can vary greatly depending on your luck)

150 TH/s = 11 days, 11 hours (can vary greatly depending on your luck)

160 TH/s = 10 days, 18 hours (can vary greatly depending on your luck)

170 TH/s = 10 days, 3 hours (can vary greatly depending on your luck)

180 TH/s = 9 days, 13 hours (can vary greatly depending on your luck)

190 TH/s = 9 days, 1 hour (can vary greatly depending on your luck)

200 TH/s = 8 days, 14 hours (can vary greatly depending on your luck)

THIS INFO ABOVE should be enough to get you started with an idea of what you need to find something in a matter of two weeks without much problem. IF you want to solve a block EACH DAY, you need the following at present difficulty:

1700 TH/s (1.7 PH/s) = 1 day (can vary greatly depending on your luck)

SLUSH'S POOL [LATELY] has averaged 6800 TH/s (6.8 PH/s) 6 hours, 4 minutes (can vary greatly depending on your luck). THAT IS FOUR (4) BLOCKS EACH DAY ON AVERAGE. However, we have been doing about 5.2 blocks each day on average the last 30 Days.

Four (4) Blocks each day x .01523747 average shares = .06094988 BTC per day x 30 days = 1.82849640 BTC

However, we have done 5.2 blocks per day for the last 30 days x .01523747 average shares = .07923484 x 30 days = 2.37704532

All of that with 4.6 TH/s Farm. I've made 0.88 BTC the last 7.5 days with this small farm. We've had a good last 7.5 days.

I have 10 more S3's on the way from Batch 10 as soon as they are available!

Hope this helps...
