Miners with low hashrate can manually adjust the difficulty to optimize performance in shares according this table:

Hash Rate (KHash/s)	Difficulty
1	+0.00000116
5	+0.00000582
10	+0.00001164
50	+0.00005821
100	+0.00011641
250	+0.00029103
500	+0.00058207
750	+0.00087310
1000	+0.00116414

Example:

For ~50 KH/s, use ICOIN_ADDRESS+0.00005821 as username (replace 'ICOIN_ADDRESS' with your real iCoin wallet address).
