Theres blockvalues.xml in confg/modular. Some weird mathematics going on in there.
From what i see its functional blocks like coal and sandstone that modify speed and efficient (sandstone should be a tad better) and then its about adjacent blocks and layers that contribute to its efficiency. netherrack and better, quartzblocks would be to mention here.
