On pool.biblepay.org at the moment (not like the previous night), some of my miners A & B appear to have a disproportionate boost in reported hashps when compared to my other miner (at least from this snapshot using reported pool hashps).

All are v1.4.3.1 and have similar conf files and importantly had the same conf files before block 123,000. Let's see if this translates into an increase in successfully mined blocks or not... (However, I can't tell from the pool though which worker mined the blocks...)

ID   OS                   Hashps (EVO)   Processor(s)      Approx hashps (EVO) with classic <123,000
A     Ubuntu 18.04   32,000             2xE5650            ~7000
B    Ubuntu 18.04     22,000             2xE5645           ~6500    
C    Windows 10 Pro  6,800              E5-2650L (ES)   ~5000

Edit: Sorry but that's all the data I have at the moment. This definitely needs a larger dataset. This data is shared so that this hypothesis (I am not making a conclusion and no one should at this stage...) can be investigated.
