How did you work out the satoshi/byte = 128?
I didn't, I failed 
I misread 200000 satoshi for 1558 bytes, but it's 100000 satoshi for 1558 bytes. That means 64 satoshi/byte, which means it will most likely take a lot longer than 24 hours.
No problem, thanks for helping me, can you confirm the formula on how are you getting to 64 satoshi/byte based on 0.001 fee and bytes been 1558?
