I have slush configured as failback pool and I keep getting tiny amounts of BTC from slush.
Not to crap on your post....or configuration for that matter...but, WHY IN HELL would you set a score-based (
or any NON-PPS/Time Based/Share Expiring) Pool as your Backup/Failover Pool ?
Wouldn't it make far more sense to use a
pure PPS Pool as your Failover/Backup Pool ? .....a pool that doesn't care when you connect, or for how long, or for how little.....still giving you FULL value for every share submitted ?
You might be pleasantly surprised when those tiny bits begin to grow in size if your need for a backup/failover continue.
Again, sorry to point that out, but someone would have....or perhaps already did and I missed reading it.
Happy Mining
