NOW 500% Referral commission
I add you faucet few days ago, and it is probably one of the biggest referral commission currently - but in my opinion you have few "problems". First is that reward is only 20 satoshi, and second that timer is 1440 minutes. This is far away from something which will attract potential users, so it would be better to increase reward, ratio 20 sat to user/100 sat to referrer is not good. You can try with 40 sat reward and 100% or 200% ref commision.
One more thing, that script is have some bug from the start - it may show that user need to wait xxxx minutes to claim even if he claim before that time.
