Ok, I see, but this condition puts smaller miners away from this pool!
Imagine that I have only 100 kH/s, which is approx. 0.2 LTC/day, so I can have 5 LTC after 25 days (at least I think...) so after that I will pay 0.1 LTC (which is 2%).
For me (as every low hashrate user) it is better to mine at pool with 2% fee and have payout of approx. 0.196 LTC every day...
For example ltcmine.ru has only 2,5% fee, but it is PPS, so you will get paid every hour and you can withdraw with lower limit 0.01 LTC anytime for free.
