I was curious about what the average user mining is doing in terms of kH/s - using the limited data available here
https://www.litecoinpool.org/poolsand then getting the total number of users from each pool i came up with this:
Pool Hashrate kH/s Users Avg kH/s per User
Coinotron 2754378 736 1,587
give-me-ltc.com 2369565 2279 1,040
ltcmine.ru 1425900 1159 1,230
litecoinpool.org 1390969 1038 1,340
notroll.in 1237648 1479 837
WeMineLTC 591427 1230 481
burnside's Pool 412011 788 523
Pool-X.eu 404663 1126 359
NuKings Pool 183170 461 397
OzCoin 154304 521 296
Mining Foreman 53890 114 473
suprnova.cc 26624 351 76
Coinpool.net 15388 90 171
MineLitecoin 13899 27 515
Total 11033836 12399 890
The average is around 890 kH/s per user - of course it would be more interesting to know the standard deviation to see what % of people actually fall within this average but I thought it's interesting especially for new miners.
