It will be best if you give your instance or go more detailed when creating a thread.
The difficulty of mining is general, no miner gets less difficulty than another. Using ASIC which is now faster than previous device makes it easier to catch new blocks and earn the rewards before others. To be clear, the difficulty in the network is always the same, since the hash rate increases due to ASIC, the network adjust its difficulty to match the average 10 minutes time of adding or finding new block.
More context:
I solo mine since 1 week, bought my NerdQaxe++, and getting interested about mining (because in UAE the electrecity cost is 0.02$/kwh [for locals]).
So on my device it's written: Best Difficulty 609M.
If i understand well, the network has a difficulty level of 127T, but your device can "reach" any diffuclty isn't it? even higher than 127T ? example: 12P ?
So i was wondering what is the world record for this "One shot best difficuly" ?
But if you tell me devices can't "One shot" above the current level of the network then no problem.
